Happened with me in the case of a pair of slippers. I purchased this leather pair from a shop near my home. It was super comfy and I was hooked. Alas it did not last forever and was in tatters some 2 years later (What else do you expect from footwear that I would have worn to bed, had not my wife given me that look). I went to the same shop for another pair but he told me that it was not available any longer! I refused to part with my old pair and continued to wear it, despite my wife's remonstrations and threats.
I was in a mall one day and saw someone else wearing the same pair. My heart jumped for secret joy! Gathering courage, I went up to the chap and asked him very sheepishly about where he got that pair. The chap gave me the biggest of the smiles and mentioned the same shop I had purchased them from. When I recounted my failed mission to purchase another pair from that shop, he responded, "यार बात तो है इस चप्पल में...मैं भी ढूंढ रहा हूँ! मिले तो बताना!" When I told my wife about my "Encounter with the Stranger in the Mall", she burst out laughing and said, "वो आपका चप्पल साथी हुआ!"
I am still searching. I found a comparable pair and was compelled to throw my old pair, but alas, the new ones don't match it so far.
