Do treat your sisters and your girl schoolmates in a gentlemanly manner. You have no idea how much it will add to your own appearance.
Do guard against a profusion of slang that would do credit to a pickpocket.
Do be determined not to use profane expressions in the presence of ladies, children, or ministers, or anywhere else.
Do keep your lips from uttering coarse and unclean things that you would blush to have overheard by mother or sister. More than this, do not listen to them from the lips of others. A pure-minded boy will be a pure-minded man.
Do take care of your various belongings; do not expect mother or sisters to pick up your necktie, your gloves, your schoolbooks, your hat, from as many different places as there are articles, and put them properly away. It is quite as necessary for boys or men to have some neatness in their habits as for girls or women. Do learn to help yourself occasionally. It is quite possible that you should be able to arrange a necktie, comb your hair, or get the articles together for a fresh toilet without calling some one to your assistance. Quite possible and vastly convenient for other members of the household.
Do close the doors without slamming; don’t tear the house down.
Do lower your voice sometimes; everyone is not deaf.
Do be neat in personal appearance; collars, handkerchiefs and cuffs, should be spotlessly clean, and hands and finger nails receive careful attention.
Do not fail to use three brushes every day—the tooth-brush, the clothes-brush and the blacking-brush.
Do break yourself of disagreeable personal habits. Do not yawn in people’s faces, lounge in your chair, scratch head or person, or clean finger-nails when others are present.
