Depends how you define friend;
As in met a few times but never really had that many conversations.. then maybe a thousand. If you mean more like, yeah, we've known each other for a while, always fun to meet each other and have a chat, then maybe a little less than a hundred. If me and the other person have known each other for a long time, share a lot of common interests, hang out every week and feel a little bored/sad if the other person isn't with me when out with other "friends" one night then probably about only ten people. Then we have online friends, people I have never met in real life but I still consider to be my friends.. I actually have quite a lot of these, across various online games, forums, social networking sites etc. I'd say over 200.
But IMO the most important kind of friends to have is ones that you are happy spending time with, the ones that you can count on, talk about various different things and just have fun with.
Nobody likes me. Everybody hates me. Guess I'll go eat worms...
Ah yes!
Wouldn't be a Zelda Dungeon thread about RL stuff without one of these!
