It's a valid topic. Saying something once definitely won't get anyone's attention. I mean, it would be great if we could all respond to constant criticism and suggestions for change by saying, "There you go again!"
"You can't keep sleeping around on me!"
"Oh, here comes this one again!"
"I'm issuing you a citation for DUI..."
"Just keep beating this horse! You're like a broken record 'don't drive drunk, don't drive drunk,' it's getting old."
