Faults shared are as comfortable as bedroom slippers and as easy to slip into.

McGinley likens shared faults to bedroom slippers: familiar, comforting, and effortless to put on. The image suggests that when a weakness, vice, or bad habit is normalized within a group—friends, family, a social circle—it stops feeling like a problem and instead becomes part of the “at-home” atmosphere. The line points to the social psychology of complicity: mutual imperfection can create solidarity, but it can also dull conscience and make self-improvement less likely. The ease of “slipping into” faults hints at how quickly people adopt the moral tone of their surroundings, especially when blame and responsibility are distributed.
