He probably simply didnt care. As long as parents were ponying up the cash, what difference did it make?
You might ask yourself the same question as to why they can berate girls there for being whores if they've had one sexual partner, God help them if they've had more then one. Yet apparently Buchi's sexual appetite is insatiable, he just can't get enough. Hypocritical much?
As to Charlie its definitly been suggested that he may be in violation of the
sex agreement
Maybe he and Buch need to be placed on bans.
