I used to feel very strange when doing anything alone. The lizard brain in me was embarrassed that I'd appear to be a loser with no friends. Then I went on a 2.5 month bike ride across the US. You get real good at being alone doing that. Hours every day spent with no company but the wind and occasional passing cars. Then you'd arrive at camp for the night and sometimes there's be other people there, but often you'd be alone. I'd go eat alone, visit museums alone, and do all the other touristy stuff I wanted alone. It was amazing. It actually made the interactions I DID have so much more meaningful. Particularly with other people doing the same bike ride I was doing. Those were such fun conversations. It's funny, being alone is a skill just like anything else and if you don't exercise it you won't be good at it :D
