Home is the place we love best and grumble the most.

The line captures a familiar domestic paradox: the home is often where affection and belonging run deepest, yet it is also where people feel safest to vent irritation and complain. Because home is intimate and routine, its imperfections are more visible, and expectations are higher; we grumble precisely because we care and because we assume the relationship can bear honesty (or impatience) that would be restrained elsewhere. Attributed to the American evangelist Billy Sunday, the aphorism fits his plainspoken, crowd-pleasing style—using everyday observation to make a moral point about gratitude, self-control, and the need to treat family with the same courtesy we extend to outsiders.
