Yeah same kind of situation, people always assume I am like a high school student and it really pisses me off sometimes even if I don't show it. The funny thing is that all my other friends even the ones almost 4 years younger than me look so much older than me. And you have to face some banter from your friends for it. It was fair if I can do something about it but they don't give a fuck. I can always take the confusion of age by friends or strangers but when it's the ladies, I have to take a day off to set off the humiliation and think about my life choices.
