Sample
ok so we have this client meeting thursday and sarah wants a deck but honestly i think a one pager is better, the client is an HVAC company, family owned, they were upset last quarter about response times which we fixed, avg ticket time went from 9h to 2h, also need to mention the new pricing but do NOT bring up the contract renewal yet legal said to wait, oh and can you make it not corporate sounding they hate that, anyway something i can send sarah tonight
Taking from this: a client-ready summary the client can skim in two minutes as a one-page PDF to send Sarah tonight, constraints: no mention of the contract renewal (legal said wait); not corporate sounding. Assuming a one-pager over a deck (flag to Sarah). Parked: last quarter's friction, as background only. Proceeding.
It caught the deck versus one-pager conflict, the legal constraint buried mid-ramble, and the real deadline: tonight for Sarah, not Thursday for the client.
