anyone else get this when they go out?

so today i went out, had to go to specsavers appointment, plus i was also switching a big wad of old 20s to new 20s.

anyways on way home group of 3 topless prettyboy lads walk past me and as they walk past close one of them jerks at me as if to feign a attack and shouts "BOOO" in my face... like total stranger for no reason.... anyone else get this type of crap when they go out? or is this just me that gets random strangers tryna intimidate me for no reason?

anyway, why the feck should a stranger even bother to interact with a random stranger they pass? especially in this way? what if i hit the guy, does he think of this? ofcourse hes probably confident as he had 2 mates with him and i was just me..... tbh if i wasnt carrying a sizable amount of money id have gladly tried to see if they could all live up to their image. as for image my brain always judges everyone as larger than me, but thinking on it perhaps they maybe larger in body but definately not in muscle tone. 1v1 with one of them would be interesting if i didnt have anything to lose on me, and perhaps if it wasnt so hot. 

i guess its just todays society and crappy upbringing of a entire generation of scum. 

anyway if anyone wants to know the town that has scum like this in, its wigan. if you want to avoid scum then avoid wigan. id guess all sizable towns are like this though? 
is it perhaps that we need to bring back smacking kids? ... smack them while they are kids so that they dont need to be smacked harder by a total stranger when they are a adult when they try intimidate that stranger?
