Into pretentious conversations, weird art, and surrealist film. I became a biologist because I liked being outside. Now, I spend so much time as a scientist that I rarely leave the lab. Some sort of cosmic irony there. When I make time for it, I still love long back-packing trips into remote wilderness areas.
Cute guys are great, but I'll take interesting over hunky anytime. That said, I'm a pretty nice guy, and I will usually approve all friend requests. However, if you have some meanly-worded statement on your site about how you don't want to get friend requests from old/femmy/ugly/fat/ethnic/pervy guys, I will deny you. Of course, if you have some criteria like that, you probably shouldn't have friended me in the first place, since I am old, fat, femmy, ugly and pervy. Also, if you are a right-wing republican, we probably won't get along very well.
I will usually try to at least comment on every friend request I receive (the above caveats not withstanding). It would be great if you'd comment back. Be aware, however, that I am a dlist slut. I friend people indiscriminately, without sending an introductory email first. I'm just all into violating social mores like that. It's the internet. What are you gonna do?
