There is one particular evening I will always remember as the angriest I have ever seen my grandmother. Even on occasions that she smacked me, she was never this infuriated.
See, I was nine or so, and she was playing Phantasy Star I on the Sega Master System. It was what she did - she had a folder with armor and weapon prices cross-referenced across planets and meticulously mapped dungeons.
She was in a particularly gnarly dungeon (I discovered later), and she'd swear under her breath when she'd fall into a trap and have to backtrack. Hours passed.
I, on the other hand, was playing with a big-wheeled dune buggy. Vroom, it went, over her shoulder! Vroom, it went, over the desk! Vroom, it went, over the Sega, tripping the reset button!
We both stared dumbly as the SEGA tones sounded... and then I ran my ass out of there, because my head was about to be piked.
