I usually don't hesitate to confront others about something that they've said or done that I'm not happy about.

The problem is this usually accomplishes nothing but them resenting me and they continue the behavior. I find the less I mention it the better. Or makes no difference in the end, I don't find it changes their behaviour, and if it does, it's short term changes. People are who they are mostly, and won't change.

I love it when people are tolerant of my bad behaviours so I think I should be more tolerant of theirs as well.
