Weber (How to Pick Up Girls, etc.) may not be quite the Woody Allen of dating gurus--but his techniques for connecting-up with the opposite sex do have, as promised, ""a simple, modest quality' that puts them within ordinary, comfortable reach. ""Millions of kind, smart, attractive, charming, entertaining, and accomplished men and women are about as courageous as deer, myself--much more often than I'd like--being one of them."" There's also a welcome absence of after-divorce angst, as well as very little palaver about getting back in circulation. (Stop-making-excuses pretty much takes care of it.) Here, instead, are places where the men heavily outnumber the women--like bike paths, hardware stores, photography courses. ""Before taking a job,"" too, ""consider how many men you'll be working with."" Weber, no snob, advises pumping gas along with selling Mercedes or BMWs. One of his most engaging icebreaker tales, in turn, is about how Des Moines divorcee Stacey, 43 and overweight, managed a first, ""impromptu"" daytime date with friendly supermarket butcher Art. (""Not far from the supermarket where Art worked, a new doughnut shop had just opened. The next time I bought meat, I asked Art if he'd tried their doughnuts yet. When he said no. . . ."") With low-pressure tips on flirting, confiding, and other relationship way-stations: one of the more becoming--and applicable--of its kind.
