A example could be:
- Why were you late to work? Because I had to get a ride to work.
- Why did you have to hitch a ride to work? Because my car wouldn't start.
- Why wouldn't your car start? Because the engine makes a banging noise.
- Why does it make a noise? Because there was no oil in the engine.
- Why no oil? Because I never checked it.
- Why didn't you complete your homework? Because I didn't have time.
- What was going on that you didn't have time? I was busy doing other things.
- Like what? Jenny came over.
- Why did Jenny come over? Because I called her.
- What did you say to her? Come over and play because I'm bored and want to play.
