Eh- Most 18 year olds don't think ahead, I tell the kids that I work with ALL the time you never know when the crap you post on facebook will come back to bite you. They still post stpiud things, including pictures that I highly doubt they'll want their future children to see. Teenagers just don't think of the future at all, at least most of them. I think we've all done some stpiud things, things that I would be REALLY ashamed to have my sons find out, things that I don't want them to do. I think the best anyone could do at this point is use it as a teaching example.
