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. I'll have you know, 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."
