sherlock series 4 ep 3
john is living back at baker street
and he comes home one night and says he has a date
sherlock is lying on the couch, staring at the ceiling, and just sighs and doesn’t answer
so john persists, “it’s where two people who like each other go out and have fun”
sherlock finally glances over, scowling, and snaps, “i know what a date is, john”
and then john says, “good, then get dressed so we can go”
