There are a number of people on my facebook from schools I've gone to in the past that don't really talk to me really, but occasionally I see stuff of theirs on my page and perhaps they see some of mine...some of them play a couple of the same facebook games I do so I have 'neighbors' or whatever on those games. Not really anyone I was super close to though.

I lost touch with one group of friends, well sort of various groups since I hung out with different people some of who didn't get along with others...but I only met most aside from one the year I ended up dropping out of college, can't even find any of the ones I would still want to talk to on facebook. Aside from that I have some family members and friends/aquantinces on my friends list and sometimes contact them that way.

Its also not a site I pay much attention to, I added a bunch of people just to have more friends on the game 'pot farm' because that way you get more free stuff for it don't really care if they see what I post or not if they really don't like me then they can delete me. But yeah I don't really post a whole lot on there sometimes I might mention something I am thinking about but usually I just post things I like such as music videos off youtube, memes I find funny and stuff like that.

Maybe some peoples still have pictures of exes if they haven't got to deleting them yet...or provided the break up went smoothly and the two are still friends or at least don't have any animosity then maybe they just don't feel the need to delete all of them. But maybe there are other reasons I am not really sure.
