Cool Coincidence

What are the odds that this could happen?

Our wedding anniversary (Tony’s and mine) falls on the same day as that of the anniversary of the in-laws of son #2, who lives in the US with his wife and son. His wife posted this on her FB wall:

"In a world of coincidences, this is the best! My and my husband's parents share the same wedding anniversary. How cool is that? It is also convenient for us because we can’t forget saying Happy Anniversary to our parents! Here’s to more anniversaries!"

So one grace day every year, Tony and I and the parents of our dear daughter-in-law receive twin greetings and twin gifts from abroad.

Yeah, how cool is that?
