I just assumed it was what I understood all kids do these days - post photos on Facebook after a party - (usually off their face as well) sure some of them are embarrassing, but they don't seem to mind. Often pretty drunk etc.
Hey, kiwi - if drugs are involved, my attitude would change bigtime - but that has little to do with the case in point (as I understand it)
If I remember rightly alcohol is a forbidden drug for 16yr olds and in an interview he admitted to being "off his face". Maybe admitted is the wrong word, boasted about it.
