Wow, I love this idea.
Sure beats taking the bathroom key (which I unconsciously did again and returned again).
Another idea: Draw a picture of your T from memory. This summer I am working with 4 & 5 year olds at a summer camp and when they miss their mommies I encourage them to draw pictures of them. I did this. I drew a picture of T sitting in his chair and then I showed it to him. He goes "very nice." I felt like such a little kid. LOL
