Why would a girl lie about not having friends?

First she said she has no friends and then she said she has some, why would she do this?

Was she testing someone? She's the socially outgoing type of person

I'm with another guy having a conversation about people having strange fetishes and coming back to their ex partner (the one's who argue and fight with you every time_. Then we went on with about people who have some difficulty making some friends.

Then she said:"I don't have any friends".

Me:"You mean work friends or outside friends?"Her:"None"

Me:"Oh"

Her:"*Silence*"

Me:"Odd, you seem to have the personality of having many friends".

Her:"Yeah, I don't have any friends. . . . I'm kidding. I have many friends".

Me:"Ah, there we go".
