I have always had a beard.
One day, I decided to shave it off. I came into the room where my 3 year old granddaughter Tiffany was and asked her, "Notice anything different?"
To which she replied, "No," with a puzzled look on her face.
I then said to her, "My beard's gone."
Now the puzzled look disappeared and the innocent eyes appeared when she said "I didn't take it!"
