I can relate to this - I often feel drained being around people too much as well. It's kind of a balancing act. I enjoy spending time with close friends, but if I'm around large groups or even sometimes small groups for too long I need time to recharge.

But anyway, yes, I agree about Medium friends :) Oftentimes I feel that the thoughts we're able to share here are more meaningful than some of the conversations I have with acquaintances in-person!
