Years ago (and I mean *years*) when my brother and I shared a room, I had the
habit of going to bed very late. Actually, 3am was typical. He was (and still
is) a heavy sleeper but occasionally he would slowly wake from his slumber
while I was undressing. When I spied his eyes opening I would reverse my
actions (usually unbuttoning my shirt) and he would think it was morning and
he was late, as usual. I would then be entertained by him dressing, half
asleep, scrambling to the bathroom and shouting loudly when he realised that it
was pitch dark outside.
This went on for many years, until I left. Perhaps he still gets dressed at 3am
out of habit :-)
