Have You Ever Got A Bad Feeling About Someone?

I know people give me the same bullshite in this thread as all the other ones I start, but I am being completely serious.

Yesterday evening a guy who used to live across the street from me stopped by my house. I haven't seen him in 10+ years. He moved away and now wants to move back around where he used to live.

The thing is... He is in his early 60s, never been married doesn't have any close family around and is kind of a hot head. He is one of those people you don't want to get stuck talking to because he will talk forever.

He use to be a mechanic at a Ford dealership for years, but he was saying how now he is on disability. And he wanted to by a house and couldn't believe how much houses cost and he might be forced to move out of his apartment

As he was talking I just got this strange feeling. He is one of those type of people, if he would get at a low point in his life, at the age he is, he would go out with a bang. Not saying he would, but I just had that moment of "it would not surprise me if he does something extreme".

Seriously, anyone ever just get a bad feeling about someone?
