Friends... such a difficult thing

I've posted a lot in the past about the uncomfortable situation of having to dump a FB or LinkedIn connection. It happens, and it's very uncomfortable.... and so my policy has been not to friend people I don't actually know pretty well. After use-testing - I've broadened that policy to be:

I don't friend people unless I know and like them well enough to want to meet them for coffee.

Just yesterday, someone from my high school sent me a FB friend request. I graduated in a very small class from a very small school. Strangely though, I do not know this person. I searched my brain... but I just don't know him. So I sent him a note asking him if he might help me remember who he was. I feel like that move (not my note) was pretty bitchy.

The online world needs an etiquette manual.
