I don't know how to ride a bike.
Now, growing up in SF, I never thought this was a big deal. There are HILLS there for Pete's sake! It's hard to pedal up HILLS.
Anyway, a friend of mine recently mentioned not knowing how to ride a bike is different if you're a boy (and not a girl) where boys should know how to ride a bike...and girls...don't need to?
I am not sure if I follow this logic.
