Help me prepare the conversation where I tell my manager I'm leaving. I want to do this professionally, not torch the relationship, and not give in to any counter-offer pressure.

MY ROLE & MANAGER: {role_and_relationship_quality_with_them}
HOW LONG I'VE BEEN HERE: {tenure}
WHY I'M ACTUALLY LEAVING: {real_reason — be honest, not corporate}
WHAT I'M TELLING THEM (can be different from the real reason): {public_reason}
NOTICE PERIOD I'M OFFERING: {weeks}
WILL I ACCEPT A COUNTER-OFFER UNDER ANY CONDITIONS: {yes/no}
NEW JOB DETAILS (if you want to share or not): {willing_to_share or not}

GIVE ME:

1. **The opening line** — the first 1-2 sentences when you sit down. Direct, no preamble.
2. **The middle** — how to explain the decision in 3 short sentences without going into detail that gives them ammunition to negotiate.
3. **Anticipated objections and the calm response to each:**
   a. 'What can we do to keep you?'
   b. 'Is this about money?'
   c. 'Can you take a week to think about it?'
   d. 'Where are you going?' (if you don't want to share)
   e. 'I'm surprised, this is really bad timing'
4. **The transition wrap-up** — how to redirect the conversation from emotions to practicalities (handover, last day, what's the plan).
5. **The closing line** — how to end the meeting on a good note.

RULES:
- Don't be apologetic. You're not doing anything wrong.
- Don't list grievances. Don't justify.
- Don't say 'I love it here but...' if you don't mean it.
- Don't promise more than you can deliver in the handover.
- Don't agree to a counter-offer in the room, even if it's tempting.
