Yes some people do get tired of the phrase.
WHAT THE F IS MEANT TO BE – Try having it “the F” be code for “it’s just the way it is now, so perhaps it’s best, instead of thinking it is bad that is that way, would be to just say that all we can do at this point is accept it and move on.” Even if that’s not the literal cosmic truth about the past, it might as well be, especially if it’s something like someone else has given up on something, since you can’t force them to change their minds.
HOW AM I SUPPOSE TO KNOW THE FUTURE – You’re not. If what happened was meant to be, that included you not knowing it was going to happen. You are forgiven for not knowing what would happen, and for everything.
