We are late for a family trip and my dad is angry. I happen to see something dripping under the car. I tell my dad that it looks like we have an oil leak. I tell my dad “It’s a good thing we didn’t hurry to leave because we wouldn’t have known about the oil leak. We get the car up on blocks so we can see the problem. We can’t find the leak and the oil is dripping all over us. Finally we realize that the oil was actually just water.
