Mumma moments-1

 My daughter has turned 3.5 and she is super talkative. So will say anything anywhere. 

As we are going through a global pandemic now, which means no school and classes online, which also means that she has become a little stubborn now.

During yesterday's class, teacher told them about domestic helpers and there was a quiz afterwards.

During the class, she was roaming around and did not listen to the teacher

Teacher- Who is this on the screen

D - I want to do an activity.

Teacher -Lets complete the quiz first and then we will do the activity.

D- No I want to do the activity now

Teacher- Beta, you answer the questions fast fast and we will do the activity.

D- Please hurry up. I am getting late for office. Lets do the activity fast. :D

Teacher ended up laughing and closing the quiz (Very few students join the morning batch so at the quiz time she was the only one in the class)

Incident 2:

I went to my mom's place yesterday and my nephew is 3 months older to my daughter who is 3.5 years old. Here is their conversation:

N is watching something in his mom's mobile:

D: Dont watch mobile otherwise you will have problem in your eyes

N: Did you get a problem in your eyes?

D: Yes, yesterday I got a problem (We took her to an eye specialist a day before for eye checkup)

N: I don't get anything as I am little Singham 

One day:

D has a sweet tooth and totally loves cakes and pastries. So yesterday H got chocolate pastries and she got totally lost for 10 mins in eating it. She finished the pastry while I was passing by.

D: Mumma, I will share my "Happy Birthday" (She calls a cake/pastry "Happy Birthday" ) with you then you also share with me.

I ignored her and went about my work.

She came to me and put the left over crumbs in my mouth with a spoon. 

D: Look,  I shared my cake with you. Now you will have to share your cake with me 

I couldn't stop laughing at her smartness.

D is getting smarter each day.Sometimes I feel she can outsmart me and everyone else in the house.

While playing with her stationary kit (Yes, she plays with the stationary kit..Arranges the pencils and do timepass for 15-20 minutes so I dont mind as I get some relief from her naughtiness for that much time)

So she keeps the crayon box to her ear like a mobile and starts talking to her Nani(Grand mother)

Yes Nani. I am fine. I want to talk to Mami(Aunt)

Mami...Yes yes...Chocolate..No No chocolate will spoil my teeth.

Ok..Candy.. I can get candy from mumma also. Ok, I will tell her.

Keeping down her imaginary phone, she starts telling me.

D: Mumma, Do you know, it was who I was talking to

Me: No beta, I have no idea.

D: I was talking to Mami and she said she wants to give me chocolate. I told her that chocolate will spoil my teeth. So she offered me candy and I told her that mumma gives me candy.

So mumma, please give me a candy.

I was looking at her with my mouth open in awe.

I was thinking I can never imagine creating a story for a candy. huh

The calls have progressed. On her imaginary phone, she gets many more calls now. She gets calls from her "Sir" as I get from my boss. She gets assigned some work. She has a small toy laptop on which she finishes her work quite quickly. When some of us are talking, and she is not getting any attention, she will hold her phone to her ear and tell everyone.

"shhh shhh. I am getting a call."

Yesterday, she was talking on the phone and saying

"Sir, I have lost my laptop. What do I do? I am not able to find it." 

And she kept down the phone. I asked her what did Sir say on this.

She said. "Sir is saying, Its all right. if you lost your laptop, dont work" 

I wish I could do that :D

One more day of love

From the day we started to talk
Words flowed like water
With the chats I never want to stop
I love you more and more each day

From the day I poured out my heart
Feelings that came like a hurricane
With the emotions that never stop
I love you more and more each day

From the day I got angry and upset
And guilt filled my heart
With a feeling I can not shove away
I love you more and more each day

From the day we came close
A day we can never forget
With a wish that will never be fulfilled
I love you more and more each day

To this day when we are in love
And each moment that we miss each other
You are a blessing in my life
I love you more and more each day

Lyrics response

Lyrics of the song "I wish I was your lover"

You know I got this feeling that I just can't hide
I try to tell you how I feel
I try to tell you but I'm me
Words don't come easily
When you get close I share them

I watch you when you smile
I watch you when you cry
And I still don't understand
I can't find the way to tell you

I wish I was your lover
I wish that you were mine
Baby I got this feeling
That I just can't hide

Don't try to run away
There's many things I wanna say
No matter how it ends
Just hold me when I tell you

I wish I was your lover
I wish that you were mine
Baby I got this feeling
That I just can't hide

I wish I was your lover
I wish that you were mine
Baby I got this feeling
That I just can't hide

Oh I need is a miracle
Oh baby all I need is you
All I need is a love you give
Oh baby…

And my response

Don't try to hide your feelings

I know what you have got inside

I am all yours darling

You have me at your side

I am sorry I had to run away

And you know the reason why

But I will always hold you

No matter where you are, I will stand by

You watch me when I smile

But I can never see you cry

You have said it all

Now you don't have to find a way

Love in itself is a miracle

Don't know it happened how

You have all my love dear

So you have to be happy now

Yes you are my lover

Yes you are the one.
