Perspective

One can only tell another what they "Think" about something; their "Idea", or the "Idea" that they have adopted.
And there are as many "Perspectives or "Ideas" as there are individuals.
So here, it would appear foolish to "Expect" others to believe "Exactly" the same way, as no two individuals have had "Exactly" the same experiences.
"Right and Wrong", are relative terms in a world of infinite perspectives and possibilities.
