No, MC, it's not the brother and sister's fault, it's yours for projecting your own relationship with your sister on them. I pushed through the first time, expecting he'll see it's his own circumstances that are abnormal, but nope. Still a judgemental out-of-touch prick. "Don't let your sister come near me" ?! First, she'll do whatever she want, she's not her brother's pet; and second, how about you take a good look at yourself before calling people's family "creepy"? Mr Big Boy here got dragged around by his sister without standing for himself, and now he think he's qualified to comment on others' relationships?
