Me- ARS(Atal residential School)...
Chairman Sir - Why
Me - Replied
Sir- tell me all technical aspects
Me- replied
Chairman Sir - dear solar panel winter mein kaam nhi krega...phir kya kroge...
Me- replied
Chairman Sir - kitne students k liye h..
Me - replied
Chairman Sir - digital classroom h sabhi??
Me- replied
Chairman Sir - what about the playground
Me- replied..
