Having unauthorized guests over, especially after curfew hours, is a serious infraction. It is important both from a safety standpoint, keeping things orderly and keeping residents out of trouble. Even a brief stay could bring with it big problems, so we frown on any infractions and take a hard line against those who break this rule. This resident has been doing fairly well in his recovery, so we weren't worried too much about contraband - he has a local girlfriend and it was obvious what the nature of the call was all about. However, as he gets reminded, the only one who is supposed to be getting it is him. It seems like he had taken this note of caution metaphorically, so when the little light clicked on in his pea-sized brain, a look of dread spread across his pretty little face.
