If I was a kid I'd love to have a pair.. can you remember being a kid?
Hell, I'm 44 and I think I'd like a pair.
I had parents that really used their imagiation when it came to christmas and birthday presents.. I got all the cool (well, cheap and cool) pogo sticks, unicycles, stilts, skateboards (before skate boards were cool). I'm sure if I was still a kid a pair of these would have been uner the tree. I would find the steepest longest hill I could find, been in the ER, and with my arm in a sling I'd have been back out on 'em the next day. My parents would have shook their heads, taken me to the ER, whined about me ruining another new shirt, or scuffing up a pair of Toughskins (you just couldn't destroy a pair of toughskins) and went shopping for whatever other evil, hurt your kid kind toy they could find.
I think it's a shame when a kid makes it to High School and has never seen the inside of an ER except for the flue (another parent story about ER uses). I've had Tonka dump trucks send me there, a chair in Sunday School, a freshly waxed floor, cool slippery socks, and a radiator did it next, falling out of trees.. bike/car accident.. tree limb stuck under the knee cap, wait, that didn't rate an ER visit, mom fixed me up.. gravel abrasion that tore a flap of skin off down to the knee cap.. broken shoulder from being stupid on the bike.. Ruined shirt from taking the skateboard down the steepest hill in Derry NH.. ohhh, and the finger I had almost cut off by falling on an empty beer bottle while wrestling my much older much bigger cousin.
I honestly can't remember a whole week going by as a kid that I didn't have a scab somewhere to pick.. elbows, knees.. palms.. Let your kid be a kid, buy them a pair of Heelies LET them hurt themselves.
At least 30 years from now they will remember the day in the restaurant when they were heeling back from the John and fell.. instead of remembering the same day as the day they defeated the last level on Halo!
