He realized his car had a flat tire
What problems did that cause you?
It made me late when I had to go work.
Problems with cars are inevitable, especially with wear items like tires. You should always try to help out if you are traveling in someone's car and they get a flat tire.
What kind of an idiot has a flat tire in the first place?
I don't think that is really his fault, I'm sure he didn't want one. Next time you should help him change the flat tire if it happens again.
