It's hurtful to deprive a person of their property.
Lance is a security guard at a sports venue and as he's frisking Todd at the entrance he finds a Swiss Army Knife that Todd's mom gave him.
Lance wants to do something about the knife.
Lance tells Todd weapons are prohibited, but he'll keep it with him and Todd can come back after the game and get it back.
Lance tells Todd weapons are prohibited, and he has to confiscate the knife and throw it away.
Todd is delighted that Lance found a good solution and promises to be back right at game's end at the same gate.
Todd is devastated because the knife has sentimental meaning and it saddens him beyond belief to lose it.
