This is supposedly a true story, told to me by a friend:
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."
