The coolest hand me down that I ever got was my first bicycle, from my older cousin. He was about 10 years older than me and I always looked up to him. He was the closest thing I had to a brother. He put new tires on it (those old balloon tires), polished the chrome and painted it a bright blue.
The bike is the very same hand me down that I've given. I actually gave it to my little cousin, the much younger brother of the same cousin that gave me the bike in the first place.
