I usually am picking up the tab, but she has felt very generous the past two times we have gone out together. Might have something to do with seeing her bank balance climbing while her friends are barely scraping by.
We don't charge her rent and there is always food here. We decided when we invited her to come home after college graduation that we had to lay some ground rules so that we could all be content. We want her to have a bank balance that can support her life as an actor so this seemed a good way to go about it. She has her own benefits from her work and puts 95% (I am not kidding here) of her salary into savings every paycheck. She helps around the house and cooks most meals and helps with the grocery shopping, occasionally picking things up that we need.
It has been a very nice arrangement so far. I will let you all know if we feel this way after another few months!
