When my wife wakes me up in the middle of the night, it’s rarely for a good reason. One night she woke me up shouting “Feel of the wall!!” I was sound asleep and wasn’t sure what she had said so when I asked she shouted again, “Feel of the wall!!” I assumed that she had been awake for a while and had a good reason for me to feel of the wall. So I reached through the headboard and placed my hand next to her hand, which was against the wall. I didn’t feel anything unusual about the wall. Before I could comment or ask why we had our hands on the wall she said, “It’s sticky! And it stinks!” That’s when I realized that she was asleep.
