My wife is very particular about her covers. She just does not sleep well unless they are perfect. Most of the time, she will just deal with her covered being less than ideal when we are at home, but she is never truly happy with the covers situation unless we are traveling.
The reason being that she loves the tightly tucked in covers at hotels.
So one night I was making the bed and I decided to tuck the covers in and surprise her.
She was happy and so I was happy.
It is these little things make help make a marriage last.
