No offense to your mom, but there's something odd about a person who irons their bedsheets. My sister-in-law does. I love her, but that's just "over the top".
Oh, that was back when sheets, etc, weren't wrinkle proof. She ironed everything. I iron as I go, but try and just buy things that don't need it in the first place.
These days, it is "over the top".
