Can you tell me what you think?

So I told my friend who is a guy that his fly was open, he fixed it and then a few hours later when I came back to say goodbye his fly was open again but after all of that we talked on the phone and I told him that I appreciated him helping me and he said “you don’t appreciate me you appreciate my zipper” please tell me what do you think about this?
