There were two women on my bus this morning who made the female cast of Sex in the City seem like genteel, discreet ladies, paragons of chastity by comparison. They were talking about things they had done in the bedroom which were not only best left behind closed doors, but just plain gross, by any definition. I can't even conceive of discussing things like this in a normal-volume speaking voice on a crowded bus.
If I'd been the driver, I'd have booted them off my bus or at least asked them to turn their conversation to a different topic, as there was at least one child riding.
One of these two women called herself a slut, and apparently she wasn't kidding. :P
