My best friend always said most men couldn't be trusted and warned me to keep my eyes open. To test my husband, who insisted he'd never stray, I slipped a pair of unfamiliar lace panties into his suit pocket. The next day, while doing laundry, I made a point of pulling them out and blowing up at him. "What the hell are these? Who were you screwing last night?" He went white, dropped to his knees, and swore he hadn't done anything. Someone must have been playing a prank, he insisted, begging for forgiveness with tears in his eyes. I secretly laughed. My little test had worked perfectly. Then I got up for water in the middle of the night and heard him whispering into his phone on the balcony. "Baby, don't put your underwear in my pocket again. My wife nearly caught me today."
