I'm extra keen on crosswords at the moment - not cryptic, sadly I've not worked those out yet - but your ordinary chaps that come in the Evening Standard. When I was living (briefly, ish) with my parents again mid-move Mum and I had some crossword-offs, and I'd get SO FURIOUS when she finished hers first. My childhood bad sportsmanship has clearly not disappeared with age, merely been repressed. When Mum gets stuck she uses a dictionary, which I say is cheating, whereas asking someone for the answer and then becoming ENRAGED when they give it is not cheating.
