A gentleman . . .

1. Keeps to the right, whether he is walking on a sidewalk, down a hallway or on the stairs.

3. . . . waits for a woman to initiate a social kiss. If she leans toward him, he turns his cheek toward her lips. And when she graces him with a light, brushing kiss, he doesn't dawdle in accepting it.

5. . . . waits until a lady at the table lifts her fork before he takes his first bite.

11. . . . never wears a bow-tie with a button-down shirt.

14. . . . is careful about what he says in e-mails. He meticulously reviews his messages, editing if necessary to make sure recipients will understand what he's saying — and the tone in which he says it.

15. . . . knows how to make a grilled cheese sandwich at 2 a.m. and an omelet at 7 a.m.

16. . . . doesn't flaunt his newest gadgets, no matter how expensive or cutting-edge they may be.

18. . . . never wears the same pair of blue jeans two days in a row.

20. . . . always offers to get up and make the coffee in the morning.
