Car Alarm

I was with a friend in a cafe when a noisy car alarm interrupted our conversation. 'What good are car alarms when no one pays any attention to them?' I wondered aloud. 'Some are quite effective,' my friend corrected me. 'Last summer, my son spent a lot of time at the neighbors'. Whenever I wanted him home, I'd go out to our driveway and jostle his car.' SHEILA MOORE
