Posting on a throw away account. My mom (52f) and I (18f) recently had an intense conversation while doing dishes. She was washing them while I was drying them and putting them away (she refuses to use the dishwasher). When I had run out of dishes to dry she told me to scrape food out of the dirty dishes to make it go faster. I didn't have a problem with this at first as I was doing nothing. However, there were well over 30 dishes that had food in them. Being a senior in highschool, my life has been so busy with school, preparing for college, and my extra ciriculars (which often span until 9-10 at night) that I'm really only home to take a shower and sleep. I'm home for dinner on Thursdays and some weekends, but I always rinse my dishes when I'm done. I also don't typically eat breakfast. So as I was scrapping these dishes with food, only a couple were mine that I forgot to rinse when I was done late at night. I have just recently injured my back and we had just gotten back from working a 8 hour shift in a concession stand for a cheer event where I had to be on my feet the whole time except for my 15 minute break to eat in which I sat on concrete stairs with my back against the wall, so my back was hurting already. And bending over to scrape all of the disgusting and rotting food (some from months ago) was killing my back more than it already was. I asked her if I could take a break because it was hurting and she told me to just suck it up because I'm going to be moving out for college and need to "learn how to handle adult responsibilities". I was mad about this response but I didn't respond and kept doing the dishes anyway. After a few more dishes, I was scrapping a pan that she had used to make scrambled eggs with of which I ate none. It was hard to get everything off and the sound was getting on my nerves so I said something to the effect of "this would be easier if you would rinse your dishes off after you used them". She didn't take this well and proceeded to yell at me for 10 minutes about how I'm disrespectful and passing people like that is not going to fly out in the real world. As I said before, I was already in pain with my back, and each dish was taking multiple minutes to scrape the food out of. I thought this was a reasonable request seeing as I was the one cleaning up after her mess. So reddit, am I the asshole for sassing my mom while doing the dishes?
