Khoa tells me that Zach noticed the name label on his door and sounded out "K" "H" "O" "A", "D" "O", realized that it was his daddy's name and asked why his name was on the door. Khoa explained that it was to tell others who sits in the room. Zach then exclaimed that he has to write his name on the door so that people will know he was in the room too! He even wrote his name in capital letters (he usually writes it in lower case) to mirror his daddy's name.
He was so excited about it and had his daddy take a picture to send to me. How gorgeous!
