On all occasions when a number of people convene together, whether indoors or out, the laws of courtesy should be obeyed. It is the duty of the gentlemen to be ever attentive to the ladies. If it be a picnic, the gentlemen will carry the luncheon, erect the swings, construct the tables, bring the water, provide the fuel for boiling the tea, etc. On the fishing excursion they will furnish the tackle, bait the hooks, row the boats, carry the fish, and furnish comfortable seats for the ladies. In gathering nuts, they will climb the trees, do the shaking, carry the nuts, and assist the ladies across the streams and over the fences.
Thomas E. Hill, Hill’s Manual of Social and Business Forms
Attention, gentlemen: it’s not enough to hold the door for the lady. You must also be prepared to construct an alfresco playground, transport trout, and scale a nut tree at any moment. This is the law of courtesy.
