They think we're sisters...
So, my female partner (sorry, she's not on the forum and I can't come up with a cute name for her yet) and I apparently look alike in some way. We frequently get asked if we're sisters--at the Y, in the stores, by our children's teachers. It's not really a big deal, but I find it creepy, and I always feel awkward after I say no, like there's more explanation required. My partner says it's just because we're very familiar with each other and people are trying to find an explanation that fits.
What do you think? What would you say when this happens? Would you just shrug it off? Would you feel creepy?
