Two persons cannot long be friends if they cannot forgive each other’s little failings.

Close company means constant exposure to someone’s small, unglamorous habits: the interrupting, the lateness, the story told for the fourth time. None of it is a betrayal, and all of it accumulates if you keep score. Friendships rarely end over the large things. They wear out from a hundred tiny unpaid debts nobody ever named.

Think of the one habit in a friend that reliably irritates you. Decide whether it is worth saying plainly and kindly once, or worth letting go of for good, since either is fine. Holding it silently while it compounds is the option that costs you the friendship.
