Addicts always say they're making a personal choice that doesn't affect anyone else, whether it's WoW or booze or blow. And they're always wrong.
The last AA meeting I went to, someone spoke for the first time and told a story about a typical night at the bar. Drinking, watching the game and minding his own business. Just like every night. Except this time, 8 beers deep, his daughter walked from home to the bar and tugged on his sleeve - there was nobody at home but her and she was scared.
Bet you'd never heard of "second-hand drinking" either.
