What is it with in laws that do not change the bed sheets?

I don’t get it. My in laws seem to think normal people that stay at their house want to use the same sheets that their kids or other people stay in. I cannot imagine that non relatives would be okay with this. I dread staying over because of this.

People that do this, why do you not change the sheets?
