You may know that you are doing the right thing at all times when offering little courtesies to others, especially to ladies, whether you know them or not.
Raising your Hat
It is not necessary to raise your hat if you see a lady of your acquantance in a public vehicle in which you are also a passenger. A little nod or smile is sufficient. Otherwise, you should always raise your hat when meeting a lady whom you know. If the lady is a close friend, raise your hat immediately she gets near; but if you do not know her very well, you should wait until she acknowledges your presence before raising your hat.
Meeting a Lady
When you meet a lady whom you know, and you wish to speak to her, do not keep her standing still. You should walk with her in the direction in which she is going. You should not offer a lady your arm when walking with her, unless you are escorting her across a busy street. You should always take the outside of the pavement when walking with a lady. You should also take the outside when walking with two ladies, and should not walk between them.
When you are introduced to a lady, it depends upon her whether you shake hands. In all circumstances the matter rests with the lady, and you should make no movement to shake hands before the lady offers hers. Men usually shake hands at the best of times.
You should raise your hat when introduced to a lady out of doors, and your right-hand glove should be removed, in case a hand is offered you. Indoors, you should never remain seated when a lady is introduced, though you need not stand to be introduced to another man.
When introduced to a lady at a dance, party or other function, you must remember, if you see her again, that recognition must come from her. You should not raise your hat, or make any sign, until she either nods or smiles at you. At a party you need not wait for an introduction before speaking to any other man present, but you should not enter into general conversation with any of the ladies until an introduction has been given.
Should lady guests arrive during your visit, rise from your seat when they enter the room, and remain standing until introduced. If the ladies leave before you, you should stand while they are maxing their departure.
