I see your points, but I don't know if I am able to stop being friends with anybody
I can't agree on one point though: I don't think she's lazy. I've known her for a long time, and she's not the kind of person who does that because of laziness. It's like with kleptomaniacs. It's not that they always want what they steal, or that they don't have money to buy it. It's an impulse they seem unable to control. The only big difference is she tries to justify her actions in an arrogant way, which is bothering.
