This fight must have been about laundry!
My wife and I both hate doing laundry, but I think that it was my wife's turn. She probably had a rough day at work and did not want to do laundry. I probably also worked did not feel like doing it either.
So we agreed to do it together, until I asked her to fold some of the clothes differently.
She was already upset and this put her over the top.
I ended up doing all the rest of the laundry.
