I hear you and definitely agree that many activities are more fun with company, but if I only did things when I had someone to do those things with, I'd never get to do anything, definitely never anything new. Why should I let the lack of companions prevent me from having the experience?

For example, I wanted to go crabbing, but none of my friends wanted to go, so I decided to go on my own, and got to share the experience with the other people out crabbing on the pier, and even exchanged phone numbers with one of them, so now I have someone to go with next time. I used to go out alone to bars, concerts, festivals, etc., all the time and always made new friends, in fact for a while I preferred doing some of those solo so that I could just totally get lost in the moment.
