What NOT to do on a rainy day!

What should you do on a rainy day?
Never ask your granny,is the first thing I’ll say.
All this happened in the first week of august,
The climate was a mixture of both rain and gust.

I saw that the rain was coming down fast,
I thought to myself-How long will this last?
For hours,I roamed around in my room.
Each minute passed and I started feeling gloom.

How to come out of this?-I had no clue.
I gave up and asked my grandma what to do.
She said,”You make me the happiest grandma alive,
Bring your brother home-Off you drive!”

On my sweet scooty,I started off to school,
successfully crossing each little pool.
As luck would have it, I fell into one,
Thanked Heavens, for I was seen by none.

Injured my leg for I hit a gravel,
Said sorry to myself and resumed my travel.
I reached the school and waited for him.
Stood there for 2 long hours with an aching limb.

Back home was safe, no landing in puddles,
My brother embraced me,just the way he cuddles.
Shocked I was, “Havent you been to school?”
“Today is sunday!”, happily he said cool.

Then I realized that she hadn’t sent me to school.
It dint struck me then for I am a real fool.
I shouted at my granny for the incomplete order,
She gave a lecture on how to listen to ppl proper.

What I’ve learnt?-Heres the clue.
Never ask your granny what to do.
