The more notable changes in the seasons have already been recorded elsewhere in this newspaper. I will limit my own observations to developments that are somewhat less obvious than the replacement of the greens of summer by the sere tans of autumn.

If you are away at work when the mail is delivered at home each day, you may not be fully aware of the extent to which each day's arrivals now tax the capacity of your mailbox.

If you have a large, rural mailbox, you're in luck. You can get your mail out of it without a struggle. But if yours is just an ordinary urban-sized box that's tacked to the side of your house, or the even smaller version that's meted out to many apartment dwellers, there may be days when you get the feeling that somebody has crammed six pounds of fish-hooks into a 5-pound bag.

One of the problems is that hardly a day passes at this time of the year without your receiving at least one large advertising ciruclar or catalogue. Comestic catalogues are especially numerous in November. I think advertisers deposit them in post officers during late summer and they breed there until the offspring emerge when cold weather sets in.

Your local mail person has apparently been instructed to bend catalogues or large advertising circulars into a "V" and then fold smaller pieces of mail inside the "V" before stuffing the entire batch into the householder's mailbox as one compact unit.

I don't know how hard the mail person must struggle to get this material in, but I do know that is November and December it is not easy to get it out.

For male readers of advanced years, another seasonal problem arises at this time of year. Toy circulars are almost as numerous as cosmetic ads, and potentially more dangerous. The government ought to require a warning on every toy advertisement: "Caution, toy ads are hazardous to your financial health and may have a damaging effect on your husband's wallet."

There is little chance that such warnings would do any good, but they're worth a try. However, I am not inclined to leave everything to Big Brother. Each individual must bear the primary responsibility for his own safety and well-being.

Grandfathers should therefore take care never to permit Grandmothers to visit toy stores alone. Grandfathers should never be too busy to go along, and by their very presence act as a restraining influence. A Grandmother on the loose in a toy store may be good for the economy, but she's a menace to a family budget.

I know only one grandfather who doesn't have this problem. After his first wife died, he remarried a sexy young dish who, for some strange reason, isn't as crazy about the grandchildren as the first wife was. There are a lot of things about life that I just don't understand.
