I know more or less how you feel. One time when I was 15 and on vacation, I went out with my older brother and sister, and we went to this bar/pool hall/disco where you had to be 16 to be allowed in (drinking laws are different here), and it was one fucking day before my birthday, but as soon as a bouncer stopped me and asked me how old I was, I jerked out "15!" and had to go.
