Also @Sheldon , taking “true” to mean “valid”, can you answer the question below?
I notice you switched from use of the word “true”, to the word “valid”.
6/7/2020 (1 day ago): Sheldon uses the word true.
6/7/2020 (1 day ago): Sheldon uses the word true again.
6/7/2020 (1 day ago): Sheldon uses the word true again.
6/7/2020 (1 day ago): Sheldon uses the word true again
7/7/2020 (suddenly today): Sheldon starts to use the word valid instead of true
Either word works by definition.
