I appreciate you
When you say 'I appreciate you,' you're really saying 'You're the worst, and I'm done with your nonsense.' But you use fancy words to make it sound like you're being kind.
My coworker said 'I appreciate you' after I spilled coffee on his shirt.
My friend said 'I appreciate you' when I broke his phone.
My boss said 'I appreciate you' after I missed three days of work.
