Working at the post office, I'm used to dealing with a moody public. So when one irate customer stormed my desk, I responded in my calmest voice, "What's the trouble?" "I went out this morning," she began, "and when I came home I found a card saying the mailman tried to deliver a package but no one was home. My husband was in all morning. He never heard a thing!" After apologizing, I got her parcel. "Oh, good," she gushed. "We've been waiting for this for ages." "What is it?" I asked. "My husband's new hearing aid."
