They have a "friends" quiz section where random questions about your FB friends- asking "Does Mary have a cute butt?". I've stopped doing this because you can see what people say about you and if you have enough points, you can see who said it. Well, someone answered that they thought I wasn't cute- it was my future brother in law. I don't know if its supposed to be all in good fun or not- but it hurt my feelings. Apparently, someone also thinks I have ugly teeth. I don't think I want to know who said that. If you think these things about me, keep it to yourself- my self esteem is already crap.
I answered a bunch of those questions, but only the positive ones- if they were negative or could be taken the wrong way, I skipped it- which is an option.
I won't defriend him, but I no longer really talk to him any more either.
