A lot of people don't know what to say on dating sites, but I have no such reservations. I freely admit to being a nerd. I won't go so far as to write you love poetry in binary (yes, I know someone who has done that), but I have been known to randomly spout out some Shakespeare. And Hawking. By no means is nerdy the only adjective that defines me - I also identify with ambitious, driven, loyal, kind, odd, and smartass.
I firmly believe that sarcasm is the highest form of humor, but only when it is enjoyed by all and not used as an instrument of exclusion. Unless I am the one being singled out - I have no problems with you teasing me as long as you can take it right back! This is actually a VERY important part of my humor.
For the Keirsey inclined, I hold strong to IN but fluctuate on the last two letters. I usually come out as an INFP, though.
