Life has scripts. Little socially-agreed plays that we enact rather than trying to figure out all our interactions from scratch every time. Many of them are very simple.
There’s the script you follow when you’re checking out at a store (“have a nice day”), the script for talking to someone who’s sad (“I’m so sorry”), and of course the script for talking to a dog (“WHOOZAGOODBOY”).
And there’s scripts for sex. Unfortunately, the most common script out there is terrible.
