Set after the 1x06 - April has finaly the chance to take a breath and think about the day she's just been through, her thoughts lead her intothinking that maybe, being selfish is not such a bed thing after all.
It's an afternoon like many others, a very boring afternoon with nothing to do but try - unintentionally, of course - to get on John's nerves. A very short slice of life at 221B.
