What about at work? That's forced interaction. (Unless you work solo)
Yeah, I guess work is included in that category for "forced interaction," but that also depends on how much energy I need to put into socializing at work. If my co-workers or boss are not complete idiots, and are enjoyable people to work with, I won't require much recharge time at all when the end of the day approaches.
A few hours every day or I get batty. I use alone time more as a reprieve from thinking than as a place for thinking about things, though. I do a lot of my thinking while interacting with other people.
Hmm. I use alone time as a reprieve to think about things or introspect. I do little to no thinking while interacting with other people. I basically can't think while I'm socializing or it won't go well. I just do it and it turns out better. I need the alone time to reflect on everything that happened and refocus.
I prefer spending time with people over alone time any day. However, I do become consumed with personal activities, like reading, which keep me engaged for hours. I tend to start feeling sick and depressed when I'm alone for too long, though. So technically, I don't really need alone time, but I purposefully spend some time alone so that I can at least do something for myself.
