I would have to think long and hard before starting a relationship with a friend's relative....unless maybe I was friends with the relative, too. (Now, doesn't that sound somewhat convoluted?

)
The guy I'm kinda crushing on right now is the brother of a friend of mine (not a SUPER close friend, but someone that I've enjoyed spending time with and gotten to know pretty well in the past year). Him and I have also become pretty good friends, too, and I don't know if anything will ever develop, but I enjoy spending time with him just as friends, as well.
I can't think of any personal experiences with anyone I know getting involved with a friend's relative, but if I think of anything, I'll let you know!
