Reading a post about a sister-in-law who visits 8 times a month makes me think of my brother-in-law

During the peak period, she used to come every single weekend, and even when we suggested going out as a family, she had no sense of boundaries and insisted on joining us. She was somewhat close to my wife even before they got married, but I never expected it to be this much. Even these days, as soon as my brother-in-law gets off work, he calls my wife every single day as if he's reporting his clock-out time. I have a sister too, but I barely even KakaoTalk her, let alone call her—maybe a handful of times a year. Their personalities are just too different; isn't this level of behavior a bit excessive? He has no social awareness, no girlfriend, and he's already in his late 30s... Sigh... I'm busy feeding the kids after work, but he makes these incredibly long phone calls. Even when I tell him loudly to go watch the kids, he won't even hang up ㅡㅡ
