Sure, I don't really understand the whole sharing thing. Or not having my way when I want it. But for the most part it hasn't held me back.
Naturally there's been one or two times in my life where it would've been nice to have a sibling. For example when my parents died. As you'd expect, an extremely tough time. It would've been nice to have somebody who knew exactly what I was going through because they were going through it too. Another tough time: when Springsteen tickets go on sale. A brother or sister would double my chances of getting the good seats.
When I tell people I'm an only child, I usually get one of two reactions. They'll say, "Oh you're so lucky." Or they'll give me a sad, sympathetic look and say, "Oh that's a shame."
It's not a shame. For the most part, it's awesome.
I have lots of friends with siblings. Some of them get along, some don't. Many of them have found a way to negotiate a truce because they have family obligations and joint decisions that have to get made, none of which happens if they're fighting like cats and dogs all the time. But it always seems like an uneasy truce.
I also have people I don't get along with. The difference is when I don't get along, I can get away. I don't worry about having to see them at home, or running into them at family events or holiday dinners.
Also, I think because I'm an only child my friendships take on even more importance in my life. Well, some of them anyway (you know who you are). I tend to invest time and energy to nourish and grow them, and find myself getting more than just a little out of sorts when that investment isn't returned in kind (you know who you are).
Anyway, I'm not making an argument for being an only child. I'm just saying there are worse things that could happen in the world.
That would be the world that revolves around me.
