My late husband was a "sheet grabber". He'd roll up in them and it would be impossible to get them back. We had an antique wooden bed and one day, as a joke, I nailed the sheet and blanket to the siderail on my side. Finally, I just gave up and got my own sheet and blanket. It cut out the nightly game of tug-of-war.And how come my wife is too weak to open a jar of pickles by herself, but when it comes to grabbing the bedsheets she turns into The Incredible Hulk??
