DEAR MISS MANNERS:
When does a gentleman offer his arm to a lady as they are walking down the street together?

GENTLE READER:
Strictly speaking, only when he can be practical assisstance to her. That is, when the way is steep, dark, crowded, or puddle-y. However, it is rather a cozy juxtapostion, less comprising than walking hand in hand, and rather enjoyable for people who are fond of each other, so Miss Manners allows some leeway in interpreting what is of practical assisstance.

These people love me just as I am, without all this fancy stuff.” Or maybe not.

They come into my house, call me pretentious to my face, criticize my stuff, complain about the way I do things, bark orders at me and try to foist their own slobby standards on me. How would they like it if I came to their houses and suggested that they try a little harder?” Yet
