fair play
Sometimes June's cousin Alice comes to visit. Alice is a couple of years older and while she doesn't like June all that much, she understands that someone has to have time for the child, and the adults have decided it will be Alice.
Alice is as patient with June as she can possibly be. She hopes that she won't use up all her patience on the goblin girl, that she'll have some left for her own children (one day). She knows June trusts her more than she does anyone else, sees her as a confidant, and Alice knows she can't rat her out unless it's something really important (like when June was seven and putting all kinds of things down the toilet until it blocked up, and nobody could figure where all that dirt came from, until Alice left an anonymous, typewritten note in someone's letterbox).
Because Alice is patient, June can play all the games no-one else will play with her. June likes to schedule lots of games, and sometimes goes to quite a lot of trouble to make them interesting (to herself, at least). One thing she likes is to have Alice choose one of her smaller toys, then she'll hide it somewhere in the house while Alice closes her eyes and counts to fifty. Then June will say "warm" or "hot" or "cool" or "cold" as Alice moves closer to or further from the object. Alice finds this game the least objectionable, but June will get impatient and grab Alice and push her in a particular direction, or else blurt out straight away that the toy is in such-and-such room. Alice likes to drag out the play, so even if she spots the item straight off, she'll pretend she hasn't seen it yet, because she knows June gets a kick out of thinking she's so good at hiding things.
Sometimes they play Scrabble. This is one of Alice's favourite games and she's quite good at it, but she knows to play down to June's level to make it fair, but then June will suddenly decide they are going to use pretend words, and then she'll make seven-letter words every turn and score something ridiculous like 630 points, while Alice will not be able to bring herself to put JUYIXON on a triple word score, so she'll finish with a modest 202 points and June will be crowing about how she's so much smarter than anybody else, and isn't her version of Scrabble just the best?
It doesn't really matter what they play: the upshot is always that June will bend the rules (or even change them from turn-to-turn) to benefit herself, and seems incapable of understanding just how infuriating it is to be the other player.
Sometimes Alice wonders if she's really helping June by being patient with her; the world is not so kind, so might it not be better for June to learn some proper life skills? But the adults are always so glad to have Alice around because it means they don't have to deal with June themselves. And Alice does like to be useful.
