Yeah, that's true. I didn't think of it that way. You're right that I would be talking about my friends if I actually had any.
I do interact with people casually, but I'm usually so busy with work that it's become a real hassle. I mean, I start at 7:00-7:30 am and end around 5:00 pm, so I'm totally wiped out by the end of the day. I'm thankfully allowed to work from home, so that cuts out the travel part, but still.
I'll look into taking classes maybe. That sounds like a good idea.

I've always wanted to learn how to do sailboating actually. But, I also wouldn't mind sitting in a few academic courses to boost my credentials.
