In the good old days, you had to walk up to a girl in a bar with a beer matt and a pencil and ask for her number.
If her friends didn’t like you… no pass.
Then you had to call her house and her mom or dad would answer the phone.
If her parents didn’t like the sound of your voice… no pass.
Today girls have DM’s and I can’t even imagine the horrors therein! I think this alone explains the collapsing birth rate.
