I get common ones:
- I look younger than I am -- unless I don't dye my grey roots, then I look a little older.
- I tend to have the "generic ethnic" look so I get mistaken for a Latina or any Mediterranean culture. I do speak some Spanish, but when in Latin American communities, they assume I speak more than I do b/c I am "one of them". Greek people think I am Greek (I know a few words). I've also been mistaken for Egyptian, Italian (I speak a little Italian), Armenian and Arabic.
The only time I wasn't happy about this was shortly after 9/11 when traveling to Europe. I was seemingly randomly chosen and went through a major security check in Frankfurt (went through all my bags, took away my passport, wouldn't let me move for over half an hour and didn't speak to me except for questioning, etc), only to be released when one security guard recognized my cultural background from my unusual middle name. The other passengers who went through this all seemed to be Muslim (women wearing hijabs) and I was asked several times if I knew any of them or if I was traveling with them. I understand security is important but it was a very uncomfortable experience.
- In university, for some reason, I was often assumed to be less intelligent than I was. I wasn't overly stylish and I went through a weight gain period for a couple of years, but when I was skinner and dressed better, I was either assumed to be not so smart, or conversely, a high-achieving student athlete. I did well in school but I was somewhere in the middle of those 2 stereotypes.
- If I am taking care of children (and I often do), people assume they are mine -- even if they are totally different looking from me, like some fair-skinned, blue-eyed, blonde girls I take care of.
