Respect, kindness, empathy and sensitivity.
It's the same as in life, treat others in the way you wish to be treated.
Beware of the need to be right, even when you're not!
If upset by a post, just say I felt....... when I read your post, so that it is easy for the other person to rephrase or explain and not go on the offensive.
Most people posting here mean well, but sometimes it is easy to be reactivated by previous experiences, that have nothing to do with the post or even by those damn hormones!
