There are times that Calvin is sad, whether it was a bad day at school, family problems, or just having a bad day. Dimitri sees Calvin upset and it makes him upset, he then remembers what his dad does when he’s sad or angry. His dad grabs Dimitri and gives him the biggest bear hug he could give him and say, “A hug a day keeps the sadness away.” So, one day when Calvin was upset about something, he grabs Calvin and gives him a big bear hug and repeats what his dad says, “A hug a day keeps the sadness away.” Whenever Dimitri does that it makes Calvin happy and melts his sadness away.
