So frustrated with my in-laws. I have cooked dinner the past two nights. I did all the cleaning up afterwards including wiping off the table, countertops, and stove. I put everyone's dishes in the sink, cleaned up all the food and put it away, swept and mopped, etc. All I expected someone else to do was do the dishes. Well, my spoiled sister-in-law decided she didn't want to do them, and her mom let's her get away with everything, so now who's stuck doing the dishes on top of keeping the rest of the house clean? Me. If this was my house, I wouldn't have a problem, but I HATE cleaning up other people's messes. I feel like there just using me as someone who cooks and cleans for them... Ugh!
