Both my grandfathers had died long before my parents met, so I never knew them.
My paternal grandfather spent most of his time away from home, avoiding his bipolar wife.
My maternal grandfather allegedly loved all things horsey - and so undoubtedly would have infected me with equinomania - but it turned out I inherited it anyway.
Way back in the day my Grandfather and I would play hide-and-seek with the tildes. He'd hide them in stocks and I would find them and sell them. It's been a great game that has lasted years after his death in 1972. He's still playing. The original Tildes keep jumping around and keep wondering where they went. Obviously, there are some he doesn't want me to sell.. ;) :)
