Pizza, TV, a cool guy who'll let us stay up late! Chris and I always chatted with Alex and were impressed by how polite and well-spoken he was. It became a ritual for Alex to come over on Saturday night. And a male babysitter, I figured, could handle the high-octane energy of Charlie, then eight, and David, two and a half. As soon as he walked through the door, my husband, Chris, and I took to him. The 16-year-old son of a woman I worked with, he looked like a stunt double for Brad Pitt in Thelma & Louise. Hiring Alex* to babysit my two little boys seemed like a brilliant idea.
