@lostinyoureyes – You answered your own question, I got some superficial connections but nothing deep. I always want something more real, but never feel like I get it. You’re looking for true connections, where a party, for most people, is about having fun in a “light” way. For them, it’s a chance to hang out and meet people.
What you’re looking for is to talk about meaningful things. Hard to do at a party. However, at the next one, see if there is anyone who is a little on the quiet side. Or, someone who tries to turn the direction of the conversation to something deeper. You may find the next party less of a let down.
May I ask, are you an introvert?
