Grammar Rant

Stop saying:
"I COULD care less"

You don't mean that.
What you mean is:
"I COULDN'T care less"

ie: You don't give a hoot. Your hootometer is at ZERO. There's no lower hoot to give, even if you wanted to. (Negative hoots do not exist).

"I could care less" means you still have a little care left.
There are still a couple of cares you've reserved for emergencies. Maybe hiding in the folds and creases of your care pocket.
But nah. Give it all away. Empty the freaking care account; scrape rock bottom; do a victory dance and boldly declare:

"I could NOT care less (than I do right now)".

Just think these things through before you say them. It's really just a matter of logic.
