I will miss you

This past saturday the big boys packed up and went to spend the night at grandma and grandpa's house. Carlos has only spent the night once and has not really declared an interest in sleeping over, so he just stays with us and Emma. He always goes out to tell them bye as they are leaving. This time he also told each one of them "I will miss you." He said it in a very sincere voice, and he was sad to see his brothers leave. I can only wonder if he will tell them the same thing when they leave to go to school every morning.
