I think what you learn with age (if you're not wise enough to notice sooner) is that a person who is truly into you doesn't make a first date some big ordeal. They're not hard to figure out. It'll be clear they just want to be around you and continue the vibes and chemistry yall demonstrated when you first met/matched up, plus all the ensuing msges/Facetimes/etc.
Whereas the ones who show more interest in the venue you're "taking" them to; barely respond to your ish; more transactional than flirtatious in tone; don't initiate; and when they do engage they say things that make you 2nd guess their interest... y'all don't got no chemistry. You may pull off a hail-mary conversion but just know you're walking in their as a free meal/drinks in their eyes..
