i am 26 and it seems like this is the age i have been since i was 10 (maturity wise). i have always been the commun sense guy that my friends ask for advice and that never does anything stupid because i already knew better (what fun is that right). it just seems like all my friends are finally on the same page as i have been for a while. i could be wrong though as it's all about the eyes you are seeing it through. ( BTW i haven't gotten the "excuse me sir" yet :)).
also, weird thing for me was that when i turned 19 and started going to the bars, i didn't get asked for ID even once until i was 24 and now i get it all the time. everyone thought i was 25 when i was 19, now i everyone thinks i am 20-21. strange but true.
