"There you have it."
Actually, "There you have it." is the focus for tonight's conversation.
What do we have?
Why do we have it?
Do we have enough of it?
Too much of it?
What's it?
Who's to say? (but that's another program)
Simply stated--"There you have it," according to Mr. Webster means "Used to draw attention to a fact or to emphasize the simplicity of a process or action" "There you have it."
