I do not see anything wrong with it....as for graduating before him, I don't think that should be a big issue, that kind of thing is fairly common in my circle. Most people I know are anywhere from 15-my age, 25 or older and as far as I can tell there is not that drastic of a difference between what teens and young adults are into. Now I will not talk about the more complicated legality stuff too much, but I have had situations where people my age to teenagers are drinking/smoking....well obviously all the teens aren't going to listen to me of I go around saying 'hey your not old enough' so kind of have to see it as they do what they do....it can be a little of a complicated issue though I suppose.

I guess just be aware of any legal risks that might come with hanging out with younger people....and use your head. For instance sure maybe an under-age person should not be drinking that beer....but better to keep an eye out for them then try to be their mom/dad and tell them what to do from what I observe then they are also more willing to slow down or be distracted from the drinking rather than be rebellious and try to show off that they can get drunk. My views may not be inline with everyone else but its what I've grown up around/experienced.
