"Hey, if I want to decide which city to move to, I still have to consider what schools my little sister's grades can get her into, right?"
"Yeah, it's up to you two to balance each other's needs. Anyway, I have a connection to get her admitted as long as her grades are good enough."
"How long have you been out of town, and you already have such connections?"
"Of course, it's because I was lucky enough to owe someone a favor. When it's something money can solve, it's no big deal. I know who to pay, while others have no clue who to bribe."
"Oh, that's good then."
"Just keep this information to yourself, don't show off to others. A favor can only be used once. If someone asks me for a connection, I won't give it, and I won't care how awkward you feel at that moment."
"I know, I know. It's about my little sister's future, I'm not that foolish."
