M:I had an argument with David yesterday.I hope he's not still mad at me.
W:What did you argue about?
M:He borrowed some money from me and I needed it back.He said he didn't have the money yet.
W:Well He should pay you back.It's only fair.
M:Yes,but I got angry with him too quickly.He probably thought that I mistrusted him.I shouldn't have got angry.
W:Did you lend him a lot of money?
M:Not much.I had to pay an unexpected Bill,so I needed the money back.
W:Well,Talk to him about it next time you see him. He probably feels as bad about it as you do.
M:I guess you are right.We should patch things up.
