Three girls of same age group were sitting in front of me

One of them tall and fair sitting in the middle looked just once at me
And started laughing
Tried very hard to stop
Not to laugh
Kept her hand and pressed her mouth
But could not stop

The other two girls from left and right looked at her
Now all were laughing together
Whole room filled with their laughter
Made the moments filled with joy
When I asked why are you laughing?
They felt embarassed
As they don't have any apparent reason

I too enjoyed and hold the moment in me
It was also laughing seizure for me
I too could not stop laughing
