Then S sir came from the next class:
S sir to A.V. : Who were laughing? Ask them to come out of their place!
A.V. : Yes sir!
S sir: Call out their name!
S sir (politely): beta call out their names!
A.V. called out all the boys who were involved and didn't took our name. S sir asked those boys to kneel down in the corridor
Simmi to me: hey we were also laughing! lets accept that.
Me: yeah, we were involved too.
Sush: yeah, lets go.
Me and Simmi: A.V. tell him (sir) that we were there too.
