This poor kid is not so sure about this whole school thing. I did the same thing on my first day of kindergarden. So much so that my mother had to sit outside the classroom the entire day. I eventually got over it. However, I did still feel like crying on the first day of each subsequent year all the way through college. It even happens now as an adult on Mondays when I start the work week.
I wish I could say it gets better kid, but it doesn’t.
