I have gone to a couple games alone because of free tickets, and it was fine. Actually had great seats too. Sometimes I like to go right when the gates open for BP to get catch some balls, so it works out. I think we all know, sometimes its hard to get a group of people to go, pay, meet up, etc. I actually got to see Pujols' first HR as an Angel @ Angel Stadium because I decided I would spend $12 and went by myself. And I was glad I did!
I went to the movies alone only one time, to see The Dark Knight Rises for a matinee on its final day in the theaters. I just felt like I should go one more time. There was only 1 other person in the theater and we stayed all the way through the credits. When it ended I said aloud "F***in' dope maaan!" and the other guy was like "hell yeah!" Hahaha..
Other things I like doing alone: shopping and going to theme parks like Six Flags. I take my time and roam as I please. Single rider line, thank you!
I have friends and a girl but sometimes its nice to just be by yourself and clear your head and get away.
Plus you can do whatever you want without anyone bitching and moaning! I actually get along great with myself!
