ok im 90% sure the post is a shitpost but if it was me when i was younger id probably wanna know how to not be an idiot
literally all u need to do is establish that ur interested in them romantically like u can straight up say 'hey i think u look rly cute can i take u on a date' if ur confident and direct the worst they can do is reject you but who cares better that than waste your time talking forever not being able to ask just to be rejected later
also if ur trying to actually learn how to talk to girls u might wanna check out the book "Models: Attract Women Through Honesty" it sounds pretty cringe but it's god some solid advice (it's written by the dude who wrote 'the subtle art of not giving a fuck')
