As long as I feel comfortable with someone I'll be an open book. When it comes to interacting with people, just be kind, respectful, and genuine. Being a chameleon, trying to be what you think other people will like, is no good because I've down that before and it doesn't make either person happy.
Generally, I like to hang out with friends - be it going out for an adventure or chilling and having casual conversations about morally ambiguous topics and pretending we're philosophers. In my opinion, good people = good times. Simple as that.
Hanging out with interesting people and trying to answer life's weird questions, like "why is the Discovery Channel becoming click-bait quality crap" or "why does it take 5 tries to get the USB cable plugged in when there's only 2 different sides?"
I'm also into outdoor activities that give you a good workout, while being fun. Doing obstacle course races (like warrior dash) is great. Fighting waves in the ocean. I'm trying to get more into rock climbing.
Oh, and trying to do more adult things like saving up for retirement, cooking, saying no to strangers with candy in unmarked vans, etc. So far, so good.
