My friend pretends to be poor when she is in fact quite wealthy. She pretends in very little, subtle ways. She talks about the all the things she can't afford, to distract from all the things she can. She has a similar level of income to me, but keeps going on and on about my "expensive house", as if its something she can't afford (her house is a similar size, just slightly less done-up). My guess is that it makes her feel like one of the people, but it drives me up the wall. How can I stop being irritated by her and just let her "do her"?
