I played piano for a couple years until one day, sometime before Christmas, I was listening to a violinist on the radio with my mom. Being eight, and suffering from severe "gimmies",

Three weeks after Christmas: I hate the violin, and my mom is just short of locking me up in a room with the violin to make me practice. That first half year, everyone was miserable: me, my parents, and my poor teacher. But things have gone uphill since then!! Now it's just my parents and teacher who are miserable! :p
Over the years, I've picked up other instruments like guitar and flute, but that's another story...
So anyways. How did you start your other instrument? Were you a kid when you started, or did you start as an adult?
