What is an analogy for assert and deny?

An analogy for "assert" and "deny" could be likening them to a light switch. When you "assert," it's like flipping the switch to the "on" position, confidently illuminating the truth of a situation. Conversely, when you "deny," it’s akin to turning the switch to "off," casting shadows over the facts and rejecting the light of reality. Both actions influence the perception of what is true or false.
