Yeah, I've no sympathy for the shop owner at all, that sort of aggression is never warranted and the interaction made me think that either the guy was trying to provoke a physical confrontation, either to have a punch up or to press charges of assault, and at one point I even thought this has got to be a training video or some shit because it cant be real.
Skater guy seems a bit old to be a skater actually and the whole thing has that strange Middle America feel about it, like the anti-social behaviour IS thoughtless but NOT threatening and the reaction to it is totally over kill and seriously infused with all kinds of rage about things other than what is simply going on at the time, I mean that guy wasnt simply aggrieved about the bush, he'd been replanting it, there was a sort of epic struggle going on there between him and his perceived foes and it really looked like the perceived foes, the skaters, where pretty ignorant of the guys grievance (but also unlikely to think about whatever had pissed him off, instead just simply that he was pissed off).
This is something I try, and fail its got to be said because I think it is about a sort of internal maturation that you cant magically accelerate as it happens at its own pace, to instill in the kids I work with. You could have a legit issue, the minute you get aggressive that doesnt matter, it ceases to be about your issue, or your anger for that matter, and becomes about your aggressive behaviour.
Back to the middle America thing, if this where to be shot in the UK, it'd feature probably a group of hooded, scrawny younger kids, they'd be smoking, sniffing solvents, possibly drinking or abusing drugs, it'd be mixed male and female, they'd very possibly be shouting swears at passers by and if anyone ran in their direction to shout at them they'd get knifed or attacked. Now it could be a BS attack, a sort of flailing "forward panic", I've seen plenty of that, but even at that all you have to do is fall and they'll be jumping up and down you on the ground. Now I reckon anyone scrutinising vids like this one and considering it anti-social doesnt know they're born to be honest.
