A little while ago I realized it was important for me (and most people) to know when not to talk. I later read in Don't Sweat the Small Stuff for Women and learened that when people come to you and want to talk or complain, it's best to ask first, "Would you like my opinion, or would you like me to just listen?"
How truthful and useful is this? I think I'll be saying this a lot to people around me, and only give my opnion when they want and ask for it. I think I'll be able to better stay out of trouble this way.
