Here is my way of thinking. I am as open as usual with people, until I suspect something or 'sense' something. If I decide something is not on the up and up, I deprive them of the most important thing I can...
ME (

, not that they ever know or care)! I just either don't even open the threads, or do not answer them. That way, if I am right I am not stressed out. And if I am wrong, the only one who ends up a losing anything is me, and that is what I deserve for being so judgemental!
