*dusting off the ledge and pulling up a seat* I've been there. I've so been there. When I was in my late 20s, my aunt used to remind me that she didn't get married until she was 29. Now that I'm 33, I'm treated like I'm the sad old spinster who can't hook a man. Luckily I have a (married, of course) friend who does understand, so I can vent to her, but it's hard.
Also, I find that as I get older, people are more interested in my cats. Am I just paranoid, or do they think that's all I have going on?
