Our hotel room in Canada had a king-size bed, which I slept on, and a pull-out sofa that my son slept on. The first night we were there, I picked out my side of the bed and went to sleep.
It wasn’t until the second night that it occurred to me: Hey I could sleep right in the middle of this bed if I want to! There’s nobody else in it!
“I still slept on my side of the bed when you were gone,” my wife said later.
