Thank the lord that there is friction if not I would not be able to ride this wheal chair and if I could not ride the wheal chair I would not be able to walk.
Let me explain why friction is very important for me. Friction helps me roll and not slide all over the place It gives me grip on the sidewalk. That way I can roll down a hill peacefully instead of crashing into something. So if we did not have friction we would not be able to do a lot of things like drive a car or ride a bike or even ride in a wheelchair.
