Ever since I got out of school has been hard to meet ladies for the same reason it was so easy to meet them when I was in school, because...how can I explain it? Because I look smart (i.e. look like a nerd) so of course the ladies would just flock all around me to study with me and have me explain the subjects and such, but going to a club now? Not the same results.
But I do think going to parties with friends are the best place to meet people because you've already been "vetted" by the friend who invited you and so the other people there there would feel more comfortable talking to you since, even if you're a stranger, a mutual friend can vouch for you and they'll trust you, so it'll be easier to take them back to your place and trap them in your basement.
