Weird coincidence
I went on a week holiday to Bad Wildbad in Schwarzwald, Germany. At one point driving there we wanted to call the family that rented the appartment to us to tell them we would be a bit later. Once I rang, my cellphone displayed the name of a colleague working in Germany. I remembered programming the number for that colleague months ago, but apparently I made a mistake in the number.

That wrong number was the number of a landlord, who was completely unrelated to that colleague and lived in a completely different town - somewhere in Schwarzwald instead of Hamburg. How weird is that?
