I think it's safe to say that Heather had much less fun than I did. Explaining how she wrecked her car would have been a whole lot of not-fun, for instance.
Can you imagine that conversation, "Well Dad I met this boy and he gave me booze and drugs and we were going out in the country to have sex and I rolled the car you bought me." I'm kind of glad I missed that one. It also explains why my father made us buy our own cars...he knew what teenaged boys were like. ;-)
