It would never occur to me to be offended about the "rude" people who ask my age! Now ask me what size bra I wear and I might be taken a little aback!
I'm turning 30 today, but women in our family tend to look a bit on the young side... at my last job most people thought I was the typical "fresh out of grad school" age of about 25 or so. My sister is very petite and is 26 now but most people think she is much younger. When she went to get a library card in her new town, the woman behind the counter asked her if she was born in the 80's or 90's!!! (She was born in 1978). She doesn't get offended necessarily but it does annoy her that she looks so young. The really funny thing about her is that even more adult clothes, haircut and makeup doesn't help as she ends up looking like a little girl who is dressing up.
On another topic, I am sooooooooo glad to hear that women in their 30's when they have kids are the norm. I was really starting to feel like something was wrong with me since I haven't had kids yet. The decision to completely switch majors with 3 years of college behind me rather than go into further debt for a major I hated plus going to grad school really set me behind the baby track.
It will be a few more years as DH and I pay off some debt so that we can comfortably afford to live on one salary. I just know too many women who had to make some really tough decisions about whether or how soon to go back to work and I would really like that decision to come from the heart and not the checking account. What REALLY drives me nuts is how many people will tell me "oh, you will NEVER be financially secure enough," like we're some kind of freaks for having certain goals that we want met so that money on one salary isn't an issue. Even the gyn I went to when we lived in MD told me back when I was 28 "If you wait too long, you will be sorry!" I thought I at least had a LITTLE time, geez!
Anyway sorry to insert my rant in there! I don't have a problem with my age but I do have a problem with people who tell me something is wrong with me because I haven't had kids yet!
