There is No Such Thing as Coincidence

There is no such thing as a coincidence. If it’s raining outside and you have water dripping from the ceiling in your upstairs bathroom, your first thought shouldn’t be a leaky pipe.
It’s funny, though, how many people will say in that situation:

“Gosh, isn’t a coincidence it’s raining and our pipes are leaking?”

Another example: “Gosh, isn’t it a coincidence the sun is burning my skin today more than ever on the same day North Korea launched a nuclear missile?”

A final example: “Gosh, isn’t it a coincidence my best friend is three months pregnant three months after my husband started taking Viagra?”

Why is it human nature to need to invent the most complicated rationale for the simplest cause and effect?
