Sure it''s ok to listen.

Sometimes that's all people need is someone to listen.

I'm really good at that. If I could keep my mouth shut, I'd be okay, but all too often, I start giving advice. It MIGHT be good advice -- but it might NOT be too.

How do I know.
That's my problem. Everyone's situation is different. What works for me just might NOT work for someone else. Then if they follow my advice, and things "go south" they could get really mad at me, and then I've lost a friend. It's best to keep my big mouth SHUT.
Boy that's hard for me.

Masking tape might be a good solution.
