Two short coincidence stories today, though one very much tongue in cheek.
"I was living in Paris, in the Neuilly area. A friend of mine travelled all the way from Portugal to see me but mislaid my address. He was still able to find me.
He actually knocked at the door of my flat saying, "Aren't you famous! Leaving the underground (as he'd managed to recall the name of the right station, Porte de Neuilly) I asked a lady passing by if she, by any chance, knew a certain Monsieur Melo."
"Yes, she said, he lives on the 3rd floor right of no. 43 Avenue de Neuilly".
She just happened to be the 'concierge' of the building!"

"During the 1950s, my grandmother lost her wedding ring whilst digging in her garden on her 40th birthday.
20 years later to the day, her daughter (my aunt) was digging in the same part of the garden and ... did her back in! Amazing." :)
