well, in the olden days, us kids would usually form the last suf during traweeh and once the imam sahab starts the prayer, our usual pushing, shoving, khee khee hhooo hooo haaa haaa would start as well until one of the buzargs would walk back and slap one of us kids. Sometimes when we knew we've realy gone over the limit with our mustyan during namaz, as soon as imam sahab says salam, all of us would run out of masjid - to avoid being part of collateral damage.
Aah! fast forward to present ... now I turn around while sitting in the first suf and think ... 'ye salay yahan namaz purrhnay aatay hein ya budmashian kurnay'
