My eyesight might be going, but my sense of smell, and hearing is very sharp. I can smell the yummyness of little kids all around. The sticky fingers and bologna is on the door handle. The scuffing feet give them away.
Grrr if only this door opened inward, I know once they saw me that they would want to read to me. I'd be really cool too, and let them pay me in bologna, and pets.
