Why do people always cry at Mormon church?

like it's some sort of contest...? —You Know It's True

I assume you're talking about the people speaking at the podium? Take your average person in the congregation. Put them in front of a large group (remember most people are terrified by this thought alone). Ask them to speak about their deepest beliefs and desires. Result: lots of tears.

If it's a contest, I don't think it's one they're consciously aware of.
