Flying Solo

This has come up a few times recently for me: Going on vacation, or just to an event, by yourself. A lot of people seem to see that as weird, or even sad, but recently someone at work said how much she enjoys it and Sassy B has expressed a desire to go on vacation by herself.
It's something that I've done quite a bit. This is what happens when most of your friends are married, or, in the case of one, live on the other side of the country. I've done, vacations, movies, concerts, even dinner by myself (I don't go to a bar alone though, that's kind of boring seeing as how I'm anti-social). Usually when someone asks about a vacation I may have mentioned, or a concert, or whatever, and then asks who I'm going with, to which I reply, just me (sometimes I'll say three of us, me, myself, and I), they'll give me a strange look, or in a couple of cases say "awww, that's sad." Why's that sad? It's something that I want to do, my friends are either unavailable, or broke, so I'm not going to miss it just because I have to fly solo.
Recently, the aforementioned person at work asked about my upcoming vacation (going to catch a concert, baseball game and visit one of my favorite places, Six Flags Magic Mountain). When I replied that I'll be going by myself, instead of the wierd look, she said "Isn't it great to go on vacation alone, no one to worry about, you just go and do what you want to do!" I was kind of taken aback since I'd never received this response before, but it was very refreshing. It also reminded me of a time that I went to Vegas for the Super Bowl with a bunch of guys. The Rams (my favorite football team) had just lost, so I wasn't in the best mood, and we're all standing around trying to decide what to do, two wanted to eat, two wanted to go back to their room, 3 wanted to gamble, but 1 at the casino we were at, 2 at the other places, and 2 wanted to go to the strip club (I had like $40 so this wasn't an option). That drove me nuts.
And not every time I'm completely alone. On the trip that I mentioned, I'm going to be staying with my cousin in California. The events I'm doing by myself, but I'll have someone to talk to at times.
I don't consider myself a very confident person, but I guess, in a way, I am since I can go out and do things on my own and not really worry about being alone.
