I like pears

My pear was talking to me this morning at breakfast.
"Please," it said, "I need your help. I've lost something very important to me, and I think you might know where it got off to."
I was a little startled to hear my pear, but I wasn't about to use silly arguments like "you can't possibly be talking," since evidence was to the contrary. Instead I asked him what it was he lost.
"It's just a little thing, a spot that I'd been working on for the past few days. You may have seen it, it was over here, on my stem-end."
"Yes, I think I have.", I said, "What an odd thing to loose, a spot."
"I know, but can you help me?"
"I think I can." I said, and finished eating my breakfast.
