If I read this right she is a Nun? If so I wouldn't give cash, I'd give her something she has to use on herself or with fellow nuns like a gift certificate to a restaurant or salon or even bakery, or day trip. Often if given cash they feel they should donate it to the church or charity if you give her something personal they don't feel as guilty using it. I'm just going on the ones I used to work with so I may be wrong to generalize.
