He Could Go No Further

David was tired as we finished up grocery shopping this morning, but stayed awake until we got back to the house. We went inside & I told him to go get on the couch while I brought things in. I used the back door, so I wasn't coming through the living room. When I went to check on him, I saw that this was as far as he'd made it before falling asleep. He was out cold, because I flipped him over, took off his overalls and changed his diaper without waking him up!
