Going going gone...(money and common sense)

Why...
Do my brains turn to mush at auctions? No matter how hard I try, if my wife and I go to an auction, I manage to find something that I cannot possibly live without. The fact I never knew there were such things as Chinese fire alarm sticks, Japanese tangerine bowls, 1850 suppository machines, or opium smokers headrests is irrelevant. Once discovered, life is not worth living without them. Once I have made that leap, I am free-falling into the money pit that is bidding. Now not only is my life incomplete without Winston Churchill's dentures or silver sugar tongs in the shape of a wishbone, but no one else can have it! Even if I promise my wife a limit at auction, seeing someone else outbidding me is as provocative as a Bernie Saunders supporter at a Trump rally. So I end up triumphant paying too much for something that in the cold light of day is as useful as a chocolate teapot (let me know if any readers have one for sale).
