Isn’t life just a series of coincidences though? Or perhaps we don’t look at it that way because we generally term something a coincidence when it is a positive thing.
For example, it was a coincidence that your daughter and her cousin saw each other at a random place and that’s very exciting. But, it would also technically be a coincidence when you are walking by someone and they stick their arm out while telling a story and end up slapping you in the face. Both examples are coincidences but I doubt anyone would categorize the latter as such. You just don’t hear people saying “What a coincidence that you hit me in the face just then because I was thinking I could use a good slap.”
That all being said, I do think that there are coincidences, and I do generally think of them as positive things. I’d like to think that people come in and out of our lives for a reason, whatever that reason may be.
