Annoyed

well this is great i offically look 12 years old .i was at the movies yesterday with my sister who is 2 years younger then me and we were going to see a movie which was over 18's ( my sister is only 17) they let her in no problem(she is 5 foot 10 and looks about 20) and they wouldnt let me in until i showed them id because they guy said i didnt even look 12 ,come on i am 19 their is no way i look7 years younger then i am even if i am small(I am only 5 foot) .and then last week i was out for dinner with my parents and the waiter asked me when i was going to be 16.I find this really annoying ,they both proceded to be shocked when i told them i was 19, sorry if i am ranting this has just been really bugging me lately. i dont think i look that young , does this happen to alot of people i guess the oposite happens to people who are really tall because people assume they are older .
