I get a little bit of teasing at work for being an "old lady" - I'm 39 and still look young-ish (I think so anyway!), but I quilt and sew as my main hobby and I've had a hip replaced; and I'm 1 of only 2 females in my department so we get teased extra for anything remotely "girly"- but it's all just good-natured ribbing and I give it as good as I get it so that's just fun; most of us have worked together for well over 10 years so it's kind of family-like. I've also had about half of them ask me if I'd make them a quilt, and anytime one of them gets married or has a kid I do make them a quilt if I know it'll be appreciated. (Working on a wedding quilt now for guy I've worked with for over 15 years!)
I think I get a kick out of being "young" for my hobby. I don't get called "young" for any reason much anymore! LOL I'm definitely younger than most people at my guild but I don't think it matters to any of us. If anything, I think the older members are glad to see new "young" members coming in. I am not quite ready to start volunteering (I feel I need to at least learn more names first!) but I'm definitely looking forward to the classes.
