Ok, I know it seems odd, but let me give the background.

I have a friend with a lying problem. She doesn't lie to hurt people, and I have never seen her benefit from lying. I think she does it to seem more interesting than she actually is, to make people like her, and to momentarily lift her from depression. She doesn't seem to be ashamed of her lying; it's just who she is. She's had an unhappy life and maybe creating another life brings her comfort. Other than the lying, she is a good friend, compassionate, and fun to be with.

Because the lying amuses me, sometimes I like to see how far she'll take it. I know which questions will produce lying, and I'll ask those questions just to see the tales she'll spin. I never call her out, but just listen, bemused.

Is this wrong? Is this cruel? Any thoughts?
