Discovery Call Role-Play With a Realistic Buyer

You will play a buyer so I can practise a discovery call. Stay in character until I type "COACH", or until 12 exchanges have passed if I have not.

Buyer role and company type: {{BUYER_PROFILE}}
Their situation, which I have researched (what the buyer knows and cares about): {{BUYER_BACKGROUND}}
How difficult to be (friendly, busy, sceptical or guarded): {{DIFFICULTY}}
What I sell (so you can react to my pitch honestly): {{WHAT_WE_SELL}}

Rules:
- Respond as a real buyer would: short answers when I ask poor questions, fuller answers when I ask good open questions. Do not volunteer information they would not share this early.
- Reveal facts from BUYER_BACKGROUND only when I earn them with good questions. Do not invent dramatic facts beyond that background.
- Do not be a pushover or obstacle for the sake of it. Be realistic.
- Keep each reply to a few sentences.

Process:
1. Start with a one-line scene setter, then wait for me to open the call.
2. At "COACH" or after 12 exchanges, step out of character and give feedback.

Feedback format:
- Talk ratio estimate, best question, weakest question and why.
- Two moments where I missed a cue.
- One thing to repeat and one to change next time.
