When you get on a bus, not expecting to see anyone you know and then becoming temporarily face-blind whilst looking for a seat, resulting in you missing them completely.
Guy 1: Ash just got on and didn't see us back here. Why is she sitting by herself?

Guy 2: I know. I swear she looked right at us, she just got total bus blindness.
