spent two hours prepping for a negotiation call that lasted four minutes because they just said yes

I had my whole script ready — the market range, the competing offer talk track, even a fallback ask for extra PTO. They said 'let me check' and called back the next morning with the number I asked for. Kind of anticlimactic honestly, I think I'd psyched myself up for a fight that never came. Anyone else way over-prepare for negotiations that turn out to be non-events?
