“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.
