I am going to try and write this as factually as possible. We have a lot of people staying over for various reasons. Partner A thinks the bed linen needs to be washed in between every guest, even if they've just slept in the bed for one night/a few hours. Partner B thinks that is unnecessary and doesn't have to be done every time.
Partner A also feels the house should be generally tidied before guests come over - stuff put away, surfaces wiped, plates/cups etc in the dishwasher instead of piled high next to the sink. Again, Partner B disagrees.
Partner A thinks 99% of people think like they do. Partner B says their parents and sister agree with them so Partner A is the weird one and has issues surrounding guests visiting.
So - who is being unreasonable?
Poll: YANBU - if you agree with Partner A
