Something to consider:
What if we all were standing out in a cold, raw rain...and for whatever reason somebody felt the need to say "It's raining!" every 5 minutes...as if we didn't know that already? Lol I mean...if it was painfully obvious to everybody else, would it still be valuable to hear somebody say that every 5 mins? Sure, they'd be 100% correct that it's raining...but after awhile...would an already miserable crowd not be justified and saying "Yes, we know!"?
