The last couple years I've had young boys asking me if I was a boy or a girl. I think the 3 year old was keying off my unshaved legs, and the 7 year old is at "that age" (he keeps asking me if I wear a bra - I don't). I did freak someone out in the restroom at a movie theater once last year while standing around in my bike helmet. I always wear men's pants or shorts and unisex shirts and have fairly short hair.

Actually, I wish I would have been mistaken for a boy on the phone in the 70s. Instead, when I answered the phone in the bike shop, people would ask to speak to a mechanic (arg!!!, as if a woman can't be a mechanic). That used to really drive me nuts. Now people are generally please to see a woman mechanic in a shop. Though one elderly man a couple months ago ask the manager if I was his wife (as if that's the only reason a woman would work in a shop). The manager handled it well by replying that I was an experienced mechanic.
