/ Another greeting card category consists \
| of those persons who send out           |
| photographs of their families every     |
| year. In the same mail that brought the |
| greetings from Marcia and Philip, my    |
| friend found such a conversation piece. |
| "My God, Lida is enormous!" she         |
| exclaimed. I don't know why women want  |
| to record each year, for two or three   |
| hundred people to see, the ravages      |
| wrought upon them, their mates, and     |
| their progeny by the artillery of time, |
| but between five and seven per cent of  |
| Christmas cards, at a rough estimate,   |
| are family groups, and even the most    |
| charitable recipient studies them for   |
| little signs of dissolution or          |
| derangement. Nothing cheers a woman     |
| more, I am afraid, than the proof that  |
| another woman is letting herself go, or |
| has lost control of her figure, or is   |
| clearly driving her husband crazy, or   |
| is obviously drinking more than is good |
| for her, or still doesn't know what to  |
| wear. Middle-aged husbands in such      |
| photographs are often described as      |
| looking "young enough to be her son,"   |
| but they don't always escape so easily, |
| and a couple opening envelopes in the   |
| season of mercy and good will sometimes |
| handle a male friend or acquaintance    |
| rather sharply. "Good Lord!" the wife   |
| will say. "Frank looks like a           |
| sex-crazed shotgun slayer, doesn't he?" |
| "Not to me," the husband may reply. "to |
| me he looks more like a Wilkes-Barre    |
| dentist who is being sought by the      |
| police in connection with the           |
| disappearance of a choir singer."       |
|                                         |
