Front wheel and back wheel

Once, a bicycle was going fast. The front wheel looked at the rear wheel and said proudly, "Hey, we're both wheels, but I'm always in front. Do you feel bad for following me?"

The rear wheel didn't say anything and kept moving silently.

Later, the bike needed fixing. While putting it back together, the owner switched the wheels.

When the bike started again, the old rear wheel looked at the new rear wheel and said, "Hey, now you see. It's not that you are more capable, but that we are in a different situation and position."

Now, the new rear wheel stayed quiet.
