Why does he say "Never mind" so much?

There's this guy I'm (kind of) friends with and AT LEAST twice, in every conversation, he would say never mind when I asked him what he just said or meant by that. I hate it! It makes it so hard to talk to him if he "never mind"s so much when I ask him about something.

Why does he do that?

Sometimes he says never mind even before he finishes the sentences.
