How many magazines did David lend to the woman?

W: David, I must say sorry to you.
M: Why?
W: Do you remember I borrowed several magazines from you last week?
M: Yes, I lent you three magazines that day.
W: But today I only can find two of them. I lost one. I’d pay it for you.
M: It doesn’t matter. They are only some old magazines. You don’t need to return them to me if you can’t find them.
W: But I’m really sorry for being so careless. I can buy another new magazine for you.
M: No, I don’t want to hear anything like that. Let’s talk about anything else.
