Are you telling me you don’t like reading lines like:

if !is_expired: refresh()

It reads super well

Better: I’ve encountered a pair of booleans that appear to be exact opposites but aren’t. To protect the guilty I’ve changed the words: isOpen and isClosed, when one is true the other is false and vice versa, EXCEPT that while something can’t be both open and closed at the same time, it is possible for something to be not open and not closed.
