This design is garbage, you clearly didn't read my brief!

I feel we've drifted slightly from the original brief. Could we review the design to ensure it aligns with our initial vision?
Before
I'm done. I quit. Don't contact me again.
After
Hi [Name] — I’m resigning effective [date]. Thank you for the opportunity. I’ll help transition my responsibilities and share documentation before I leave.
Before
I want to get you a gift but I have no idea what you want. Just tell me.
After
I’d love to surprise you with something you’ll actually enjoy. If you were to pick one thing you’ve been wanting lately, what would it be?
Before
Let's take this offline and circle back next week.
