I am 35 years old, but was born with the mixed genetic blessing of always looking far younger than my actual age. I still regularly get asked for ID in pubs and even at the cinema. I have a DD and people tend to assume I am a (very) young mother.
And yes, sometimes this is nice and flattering.
But like all women, and especially young women, I seem to get patronised a lot. I especially notice it at my DDs school (and before that with the HV), or in semi-formal settings.
I have a PhD and have never used my dr title outside of work, because I don't want to seem like a twat, basically. But sometimes I feel seeming like an obnoxious twat might be preferable to having to put up with this general condescension. Perhaps if I start introducing myself as Dr Fyette I will be taken more seriously? AIBU?
(Mind you: I do not think young women without a PhD deserve to be patronised any more than I do.)
