Learn to Ride a bicycle

Yes, I know. You should be asking yourself : isnt she big enough to know how to do it?. Well no. No matter my age I do not know how to do it!.I think it is because when I was little I fall from my tricycle so bad I had an cast for almost 2 mounths and I still have a scar in my ritgh ankle. So Im really insecure when I try to learn but I hope to do it someday!
