What is one thing you will never do again?

The one thing I will never do again is to get involved in a topic or issue, that I clearly don’t belong in. I did this with a close friend of mine, by asking her about something that was bothering her (not knowing that it was still bothering her and that she was very upset) I made her cry. I thought that I was being helpful, and that if she’d talk to me that she may be able to fill me in on the issue which concerned my cousin. As a result I tend to keep myself quiet.
