Oh definitely. Personally, I wouldn't mind being in a relationship but it's not a priority. I'm not sure why people so often ask if I have a boyfriend, why they think it matters. I'm not sure why they'd assume I'm straight, for that matter. I don't like that kind of heterosexist presumption. One of our Irish relatives kept insisting I would be married by the time she next saw me. This is highly unlikely. Even if I found a woman/man to be with, which in itself seems unlikely at the moment, I have no desire to get married. Ever. And 21 is way too young to be thinking of marriage, ugh! Who wants to be a 'wife' at 21? And don't even mention children. Even if I wanted any, the idea of having them at this age would make me sick.
I'm waiting for the drama surrounding my childfree status in a few years. I'm quite sure I'll never want children, and I'm quite sure a lot of people only have them because it's 'just what you do'. I'm sure I'll get bingoed a few times. Personally I don't understand why anyone would want children, but I accept that they do. They should do the same with me and my desire not to procreate. I just don't like children. I'm sure there are enough mindless breeders out there to ensure the survival of the human race, so why should my decision not to have babies be an issue?
I think around the holidays will definitely be a time that you'd feel ostrasized, especially if you're single. Maybe less so if you're in a relationship but are childfree, because at least you've got that common bond with your partner there. For me, Christmas is the time when I'm reminded more than ever why I don't want children. But I think people who are less certain of what they want may find themselves caving into the pressure around this time of year.
But then I don't really know. I spend holidays with my family, and my family aren't the type to pressure me or anyone else to get married and have babies. And for that I'm thankful.
