It's a story about the destruction of alcoholism on families. I imagined that the big triangle is the parent of the small triangle. The small triangle and circle are children and nonchalantly go to play in the yard of the triangle's home (a rectangle with a door). The big triangle is crazy from alcohol and tries to attack the children. The small triangle and circle escape the big triangle and celebrate at the end.
