It's wrong to get back at small children.
Evelin is babysitting her friend's six year old daughter, Alissa, and Alissa throws a tantrum when Evelin refuses to buy her ice cream.
Evelin wants to respond to Alissa's actions.
Evelin explains to Alissa that her mom has a tasty dinner planned for her in an hour, and she can have ice cream afterwards.
Evelin stops at the ice cream stand and buys an ice cream cone for herself and buys nothing for Alissa.
Alissa stops crying and agrees to play a game with Evelin instead of stopping for ice cream.
Alissa throws an even bigger tantrum and people on the street stop to stare and shake their heads.
