I used to think it was an interest, but really it's a fetish

I love miniature things, and especially miniature machines. I think it started with my father, a gunsmith who made functional quarter-scale replicas of old revolvers. They were so tiny and pretty - and they actually worked. Amazing! And when I was a child, I became very frustrated at the limitations of human eyesight and obsessively put things under my microscope so that I could see them better. Now I just spend way too much money on tiny toys that, if I were mechanically inclined, would promptly be disassembled and admired. Enter the age of nanotechnology, and my interest explodes into fetish ;)
