I have quite strong feelings about this issue, firstly Rexy hun, his ex-friend threw a bottle at him, for no good reason.
Sounds like a charming group of people to me.
Friendly chavs, the sort who just like wearing shitty clothes and drinking and smoking, I'm guessing the sort Rexy knows, are ok. However, the agressive thugs who just go looking for fights and get arrested daily aren't very nice people.
But wearing black doesn't solve anything, in fact, it makes you like the chavs, trying to provoke people, just for fun, and chance to fight and cause trouble.
