What are the odds?

A funny thing happened on my way to a yard sale:  I found one of my old lamps for sale!  I walked up their driveway and exclaimed, "That's my lamp!  I made that lamp!"  No doubt  I had everyone's attention within hearing range.  It was then that your father got out of the car and walked up to the lamp.  (He had kindly consented to accompany me because my yard-saling-buddy had opted out.)   Yes, it definitely was one of the ones I had made at our house on West Holland Drive; the ones your father had wired; the ones we had used for maybe 20 years; the ones we had retired and sent away--where and when escaped us.  Was it CA?  I think it was because we bought new lamps when we visited Granny back in her condo near the Lamps Plus store.  Could the lamp have made the 1200 mile journey to Cody just to end up at a yard sale that we happened into?  What are the odds?
