XX audio micro-course (transcript)
Podcast 1 — Introduction & meaning
Narrator: Today's term is "xx" — an informal symbol, spoken as "double-ex", /ˌdʌb.əlˈeks/, used at the end of messages.
Narrator: In texts, cards, and notes, "xx" stands for kisses — a warm, friendly way to sign off to someone close.
Narrator: In plain English, each "x" is a kiss, so "xx" means two kisses, a casual, affectionate goodbye.
Narrator: The single "x" as a kiss dates back centuries, used at the bottom of letters as a mark of affection.
Narrator: It may come from sealing letters with a cross and a kiss, or the X-shape of crossed lips — stories differ.
Narrator: Today, the number of x's signals warmth: one x is friendly, while "xxx" feels extra affectionate.
Narrator: It's almost always lowercase in this use — "xx" — and lives in informal, personal messages, not formal ones.
Narrator: In tone it's warm, casual, and friendly — a tiny sign-off that adds affection to a message.
Narrator: So remember: "xx" means two kisses — a warm, informal sign-off for friends, family, and loved ones.

Podcast 2 — In conversation
Speaker A: My mum always ends her texts with "xx" — it's so sweet.
Speaker B: Ah, "xx" — two little kisses to sign off. Lovely habit.
Speaker A: Exactly. I add "xx" to friends, but just one "x" for workmates.
Speaker B: That's the use — each "x" is a kiss, so "xx" is two.
Speaker A: Right. And more x's means more warmth, doesn't it?
Speaker B: Yes — "x" is friendly, "xxx" feels extra affectionate.
Speaker A: The mistake is using "xx" in a formal work email.
Speaker B: Good point — it's strictly casual, for personal messages.
Speaker A: And it's lowercase, isn't it — not capital X's?
Speaker B: Exactly — "xx" in lowercase is the usual, gentle form.
Speaker A: So I'd end a text to a friend with "see you soon xx".
Speaker B: Perfect — warm, friendly, and clear.
Podcast 3 — Prompt engineering
Speaker B: Let's use "xx" as a memorable keyword for warm, friendly, personal touches in messaging apps.
Speaker A: So "xx" tells the AI I want a warm, friendly tone?
Speaker B: Exactly. For a messaging app, you'd prompt:
Prompt: Build a friendly messaging app where users sign off with a warm xx, with soft rounded bubbles, gentle colours, and a layout that feels personal and cosy.
Speaker B: The word "xx" sets a warm, affectionate, personal mood.
Speaker A: Sweet. What about a greetings card maker?
Speaker B: Try this:
Prompt: Build a card maker where users write a message and add an xx sign-off, with soft colours, friendly fonts, and a clean preview, in a warm, gentle theme.
Speaker A: So it feels heartfelt. And the data?
Speaker B: Here's a schema prompt:
Prompt: Design a database schema for a messages app, storing senders, recipients, message text, and timestamps, with clear relations and indexes for fast threads.
Speaker A: I like how personal that feels.
Speaker B: For a full build, stay minimal:
Prompt: Build a small notes-to-loved-ones app with a warm xx feel: a home page, a message list, and a single message view, all under one cosy navigation bar.
Speaker A: Could it warm up a cold tone?
Speaker B: Yes:
Prompt: Review my app's wording and give it a warm xx tone: friendly, kind, and personal, while keeping every message clear and easy to read.
Speaker A: So "xx" keeps every prompt warm and friendly.
Speaker B: Exactly — one little sign-off that adds real warmth to a design.
