I've gone to a movie alone once, and I felt very uncomfortable. Even though it isn't a social event, I still enjoy having someone to bounce thoughts about a movie off of immediately after the show. Also, since evenings are really the only time I can go to see movies, I was very nervous walking out in the parking lot by myself in the dark. If I'm going somewhere at night I try to always have someone with me.

As far as dinner... if I'm eating alone, I'll usually eat at home. However, if I do want to go out, I'll usually get take-out and bring it home, or I'll get fast food, eat quickly, and then go. Eating alone in a restaurant tends to bring on unwelcome advances from smarmy men, in my experience!

As far as a bar or a club: NEVER, unless I'm meeting someone there. And even then I'll try to make sure that I leave late enough so that they are there before me. There have been plenty of times where I've felt like going out by myself, especially when I was single... but haven't because A) women alone at bars always seem to have a "desperate" air about them, and B) it's very dangerous!!!
