I was hoping to get compensated from my long-term house guests.
What ended up happening to the house guests that you had?
You switch roles so fast, buddy! I get tired of being the housekeeper and I want a payback from you!
Did you discuss this with them beforehand? It would be a little awkward to spring this on them after the fact.
I said that I don't care.
Well unless you agreed with your houseguest for them to pay you, it is not very fair to expect them to give you money. It may be helpful to be more upfront with them.
