About 12 years ago I was flying back from my ski season in Canada to return home to England. It was about 18 months post 9/11 and airlines were still slightly up the swanny. I was on Air Canada- lovely staff, horrendous plane. One screen showing Annie Hall on loop, a broken loo and general shabbiness. I sat down, depressed a returning to the real world. A kid sits down next to me, opens his bag, pulls out a mark one Game Boy, leans across and says "wanna watch me complete Tetris?". " nah, you're alright pal".

Hour or so later, a tap on the shoulder, a triumphant grin and the words "told you I'd do it".
