Have teams line up at one end of a large room or hall. Put a box for each team midway across the room in front of each team. The first person on each team, on your command, runs to the barrel and crawls through it. After everyone has gotten through, the entire team runs to the barrel together. The first team back to their starting line wins.
Pets give people pleasure and can quickly gain their affection.
They become special. Sometimes we coddle certain sins in our lives that same way. They give us a degree of pleasure. It seems rewarding to hang onto them. They are things we enjoy doing, at least at the moment, even though we know they are wrong.
