all this talk about harming someone is funny. if youre going to do it, then just do it.
Its too easy to say, if it happened to me i'd kill him or i'd snap, etc. it's a different story when you really have to deal with it.
Though it was a different type of situation, I have dealt with it before in the past when one of my ex-wife's co-workers was harassing and stalking her. Her employer and the police could/would do little about it. It's one of those ridiculous things where he had to actually harm her physically or overtly threaten her in front of a witness before they could do anything about it. So I took it upon myself to have a "nice chat" with the fellow. I told him in no uncertain terms that what he was doing was wrong, unappreciated and needed to stop before things escalated and he wound up regretting he were ever born. Problem solved.
That said, I don't see many people in here exactly calling for Neil to go and actually harm the guy physically.
