This morning as I was getting ready for work, I couldn't help but notice our two Portuguese Water Dogs dead to the world. They were stretched out across the bottom of the bed. Addie was almost hanging off the bed and Ahna was resting on Addie. This scene reminded me of the old saying, "Let sleeping dogs lie." While I understand the meaning of the phrase, I am never sure whether to use lie or lay. It is one of those grammatical points that I need to look up over and over again. Do you have one of those tricky points?
