Definitely. So much pressure from every direction. It's ridiculous. The status quo isn't for everyone. A lot of people are better off single and/or child-free, but society seems to think otherwise. Apparently you're defective if you prefer solitude.
As for the holidays... I think the pressure might be worse for some people, because that's when you typically see family more often, and then your nosy aunt Edna who always wears that gaudy sequined reindeer sweater and too much eyeshadow waddles up to you and gives you a lecture about how the clock is ticking, and you'd better find a man soon before your ovaries shrivel up. (Note: I do not have an aunt like this. I think most of my relatives, or at least the ones who know me well, don't expect me to be like my cousins and marry young and start popping out babies. Although at Thanksgiving, my 10-year-old cousin Kara was bugging me to have kids.)
But the real pressure is in February, when Santa gets kicked out of stores in favor of Pepto Bismol pink hearts everywhere. The utter mushiness is nauseating. On the other hand, if you're in the mood for fancy chocolates, the 15th is a great time to shop for them.
I like being single. I'm better off this way. And I'd much rather be a crazy cat lady than spend decades chasing after snot-nosed, screaming children and saying "Put your coat on! Get down from there! Untie your brother!" Screw you, society. I'm not going to stick to the status quo.
