We bought a wireless printer to put upstairs in the office/3rd bedroom. Since we bought it 6 weeks ago, it has sat, plugged in and paperless, without being used, on the floor while we look for a small table on which to set it up permanently.
Last night she's sat downstairs on her laptop and pressed 'print'. 5 mins later she says "can you go up and get my printing?".
Now I hadn't seen her move in half an hour so I was suspicious but I went upstairs anyway... to find everything in darkness, the printer switched off and the printer paper in the cupboard.
A shout from downstairs "it says 'printer not responding'".
Having turned it all on, fed it paper and retrieved the now-printed docs I go back downstairs.
"It doesn't work if it's not switched on and loaded babe"
"Oh, I thought it would turn itself on" she says.
My pointing out that the washing machine doesn't load itself and turn itself on was, apparently, "not helpful".
