Is this just a coincidence ?

My friends with benefits called me through messenger yesterday and I missed the call. I tried calling him back and got no answer.
Later on in the day I just happened to see his post on Facebook.
It is a meme but he did not share it he typed it himself.This is what he posted:
Facts, fellas if her conversations are getting shorter with you , it’s getting longer with someone else. He also added I don’t know maybe God or Bob.

Bob is just the name I chose for the story but the name he used was my other male friend.It seemed kind of strange and maybe it is nothing. I was kind of startled as of why he said on Facebook.
