My sister and my motorcycle

I taught my sister to ride my motorcycle. She came back an hour later pushing the bike -- she needed more gas.

My sis did something of a like the first time out after her test. She was stuck claiming the engine wouldn't start - Cars tend not to when there's no petrol in the tank.

Its just a funny occurance. It has no deeper meaning.
