The perils of RPS:
Spending the afternoon reading figureskating slash, and then realizing you are expected to spend the evening making small talk with the dear, white-haired old grandmother of a member of the US men's figure skating team, who trains with Johnny Weir's old coach, no less. When said grandmother has just come back from an event at the rink where a significant proportion of the porn you have been reading was set.

OOPS.

(Luckily, she's mostly deaf, so I didn't actually have to say anything in order to carry on the conversation.)
