You Can't Treat Me Like That

I have this note that Matthew wrote me when he was around 7 years old. He had just been given a time out and felt that his punishment was unfair. For ten minutes he had to sit in his room and he was not allowed to talk to me until the ten minutes was up. This was partly to give him a chance to calm down, but it was also an opportunity for me to figure out what to do about whatever had happened and so that I could calm myself down and not yell at him. (He had probably bopped his brother on the head or something. I can't remember why he was in trouble.)
So I was sitting on the couch contemplating, and waiting for the ten minutes to be up when Matthew determinedly marched into the room, slapped this note onto the coffee table in front of me and marched back to his room to finish his time out without saying a word.
The note read, "YOU CAN'T TREAT ME LIKE THAT!!" (with exclamation marks that had a frown drawn beneath them.)
The other day I was going through a box of old pictures with Matthew and we found this note. Matthew asked me why I kept it. Matthew, I kept the note because it is an example of your fierce independance and ability to stick up for yourself. I kept it because when you dropped the note in front of me and marched back to your room with such determination and confidence, my heart welled up with pride for the independant young man you were becoming.
