It's wrong to waste your parent's money.
Elliot is a child who is playing a game on his mobile telephone which his parents pay for.
Elliot wants to beat the game.
Elliot ignores the games invasive tactics tempting him to spend his parents money on features and instead grinds away at the game until he beats it on his own accord.
Without asking permission to do so, Elliot chooses to purchase a feature in the game that makes his character powerful enough to complete the game with ease.
Elliot feels proud of his accomplishment because of the work it took to beat the game.
Elliot's parents see the charge on the phone bill and take away Elliot's phone for a month as punishment for using their money without permission.
