There are three insidious words being constantly overused, specifically in terms of dating.
"You never know."
This simple statement is the go-to persuasive argument for any sort of inconvenient or frustrating outing.
Singles event? "You never know." Shadchan stalking? "You never know." Online dating? "You never know."
What follows is, where does it end?
Maybe I should sit in different train cars every day. Maybe I should walk aimlessly through various minyanim. Maybe I should sabotage my car and act all helpless by the roadside. After all, "You never know."
There is also an underlying insinuation of an irreligious mindset which I find disturbing.
The Eibishter established the concept of hishtadlus - one must do one's part. Not "You never know," but the minimum requirement that the Eibishter sees as one's part of the deal. He delivers the rest. There aren't different levels of hishtadlus for everyone; just sometimes Hashem holds off for His own reasons.
I do not have to flagellate my dignity, suffer fools, nor chase perceived saviors. Why should anyone treat me with respect if I don't?
Maybe I don't know. And I prefer it that way.
