"Because you don't fucking know me"

I hate this sort of thing, I know exactly the feeling that this sort of situation gives you, a feeling of helplessness 'why won't you just listen to me instead of jumping down my throat, you stupid stupid fuck' ... that whole thing where people just assume you're knocking them or being aggressive toward them, when you're not, that seems to be a product of their own inner anger reflected onto you.

I'm certain I've had something similar happen to me. And I have to say, they're always nutters, people stupefied by their own shit lives who can't actually decipher when someone is being positive and when someone isn't, they just basically want a ruck with the world all the fucking time, and whatever you say to them you just look like a do-gooder middle class softy in the true Beano sense of the word.

repped.

This has happened to me countless times, really! You describe it well, so many people in auto-aggression mode. Girl gang's are by far the worst for this.

A lot of times however, people use it merely as an opportunity to start a fight/rob someone. This is more the case with young blokes. Older blokes who are like this are more like crackheads with serious psychological issues. But the teenage girl-gang types really really are suspicious of everything. Just looking their way is a deep insult.
