False or thing = thing
Thanks for your response and for the rules, but for some reason I'm

The first argument was "True", so "True" was returned and negated by
the "not" with a final result of "False" for the expression.
Is this correct?
Yes. Its called Short Circuit Evaluation.

True or thing = True
False or thing = thing
