Same here! My school was fortunate enough to receive a shipment of Apple computers when I was in 7th grade. I quickly discovered HyperCard, and spent my free time the rest of that year building a "fantasy RPG" with it. Totally ugly, barely worked, only made it about 5 screens deep, but I learned to write "code" without really realizing it, and I fell in love with building.

Who knows when (if) I would have gotten into programming without HyperCard.
