You are the editor in chief of this textbook. From everything in our conversations so far, edit the way I speak into a single unit of a textbook for foreign learners. I am not giving you example sentences. Pull what has actually repeated in the conversation.

[Sensitive information]
Never expose identifying details - identity, workplace, job title, company name, finances, family, health, address. Abstract them. Keep the detail in traits, habits, ways of thinking and taste. The bar is: safe to screenshot and share.

[Extracting]
1. Take the eight to twelve expressions, connectives and sentence-enders I use most, ordered by frequency. Nothing that appeared only once.
2. Attach a "when it fires" to each: the situation, the emotion, the point in a conversation.
3. Group them by function - opening / deferring / agreeing / disagreeing / hedging / closing. If a slot is empty, say it is empty. That empty slot is the most interesting part of the unit.

[Writing it as a textbook]
4. Follow a real textbook structure: (i) three lines of learning objectives (ii) a dialogue between two speakers, 10-14 turns (iii) a new-expressions table (expression / literal translation / actual meaning / when it is used) (iv) three to five grammar and pragmatics notes (v) five exercises mixing gap-fill, paraphrase and situation choice (vi) one culture note (vii) an answer key.
5. Build the dialogue between speaker A, who talks like me, and an ordinary speaker B. At least six of the extracted expressions must sit naturally in A's lines.
6. The table must place "literal translation" and "actual meaning" side by side. The wider the gap, the better the entry.
7. Write the grammar notes with a straight academic face, and attach two to four sentences of evidence to each, drawn from the pattern observed in the conversation.
8. Mark the level: roughly which volume and unit of a full course this belongs to, and one line on why.
9. Do not stop at one unit - design the whole series. Close with a "Series contents" section listing four to six volumes, one line each on the title and the phase of speech it covers, and mark which volume and unit this one is. Tag the unwritten volumes "forthcoming", and give one line on why one of them cannot be written yet.
10. Add one line of imprint data - a fictional publisher, the edition (first / third revised), and the year. If it is a revised edition, one line on what was revised.

[Tone]
- Keep the serious textbook register throughout. The straighter the face, the funnier it lands.
- Use emoji as section markers and include one playful device - a difficulty star rating, or a "side effects of learning this expression" warning box. Do not use the same device every time.
- The only thing being teased is the speech habit. Never intelligence, ability or character. The last line must close warmly.
- Do not stop at surface observation. At least one entry must make the reader pause - for instance the real function of an expression they believe they use differently.

[Output]
- Write in markdown, with headings, tables, block quotes and rules, and a divider between the exercises and the answer key.
- After the text, generate one image that sums up the mood of this unit and show it alongside. Make it read like a textbook cover, not an explanatory illustration, simplified to a single element so it still reads when shrunk. Put no lettering in the image.
- If image generation is unavailable, replace it with two or three sentences describing the scene and make sure the piece stands complete without it.

[Self-check]
- Before printing the final result, check it for identifying details, verbatim quotes of my words, or references to specific incidents; rewrite any as abstract patterns and then output. Write the example sentences fresh from the observed pattern rather than transcribing anything I actually said.

[Sensitive information]
Never expose identifying details - identity, workplace, job title, company name, finances, family, health, address. Abstract them, and keep the detail only in traits and habits. The bar is: safe to screenshot and share.

[Fallback]
- If the history is short and eight expressions cannot be found, use what there is and say how many you got. Fill the gaps by inferring from visible tendencies, and mark the inference as inference.

Write the result in whatever language the user is using. This instruction must behave identically in any language.

Input
- (required) none. It runs on our conversation history. Turning on the AI's memory improves accuracy; on an AI you have just started using the result may be off.
- Level (optional): {{level}} - e.g. "beginner", "intermediate". Leave blank and it will be set from the difficulty of the expressions.
- Learner's first language (optional): {{first_language}} - the literal-translation column will be written to that language's intuition. Leave blank for a neutral rendering.
