Yet what good will it do to point out to them their mistakes?
If your husband or son tells several people that he met John Smith last week in New York, and you know that he was in that city three weeks ago, why correct him?
He is talking hastily and does not stop to measure his words or time.

The mistake is unimportant.

Why antagonize a man by exclaiming: "My dear John! This is the third week in January, and you went to New York immediately after Christmas." When you hear your friend tell your favorite story, and change some minor detail, she will love you not a whit the more if you correct her with-- "No, Mary! the way it happened was this"-- and then proceed with the tale in the manner which you consider best.
There are so many things which we all do for which there is no honest reason, that I will mention only one more.

That is the exceedingly uncomfortable trick of reminding a man of something he has once said, when he has since had occasion to change his mind.

Perhaps some years ago when you first met your now dear friend, you thought her manner affected, and did not hesitate to mention the fact to your family.
Since then you have become so well acquainted with her delightful points that you forget your early impression of her.
