A Mistake??????

I am greatly confused by an article I just read. It said Michael Phelps made a "mistake" when he took a hit off a bong at a party. Hmmmmm.....exactly, how is that a mistake???????? Did he not know what a bong was? Did he not know what was in the bong??? Was he tricked into thinking this might be some new kind of aromatherapy? I am guessing he reached for the bong...took it into his hands....and took a hit off of it. A deliberate action. I just don't get the mistake part. It was a bad choice. It was breaking the law. It was a ridiculous trade for millions of dollars of endorsements, but it wasn't a mistake. I am sad and disapointed in this situation. Not because I'm a prude or anything else....it's just that when you have a whole world looking up to you, doesn't that carry a little bit of responsibility with it? When companies have pledged millions of dollars to you for promoting their products, isn't that worth something? Is the enticement of a high worth more than that? If he needs a rush, watch the video of his wins....that should be a bit of a kick. And the...."it won't happen again". Well, I think he said the same thing in Salisbury when he was visiting the high schools here after a DUI. But, I guess that was a "mistake" too.... Very sad.
