“When do you go running?”
“When the time is right.”
“When is the time right?”
“When it’s a nice day, and I’ve finished my work, and I haven’t just eaten, and I’m feeling energetic.”
“Repeat that last sentence, changing ‘and’ to ‘or’.”
“When it’s a nice day, OR I’ve finished my work, OR I haven’t just eaten, OR I’m feeling energetic.”
“That sounds like a better plan.”
Got a list of conditions you need satisfied before you do something?
Try changing and to or.
