Pick one specific, low-effort topic she can have an opinion on in a sentence, and say it with a straight face. "The best sandwich in this city. I have a ranking and I will defend it" works. It gives her the job the prompt promised, an easy way to begin, and a hint of how you talk. The answer is not "anything you want" and not a deep question. It is a small topic with a little attitude.

What this prompt is really asking

Read the stem as a trade. She starts, you choose. That is a playful deal, and your answer has to keep up your end of it, which means naming the subject you are offering.

It also lowers the effort of the first move. The hardest part of starting a chat with a stranger is picking something to say. This prompt removes that, so your answer should make it easy for her to take the first step. If it is vague, you have taken back what you promised.

Pick a topic she can answer in one line

A good topic has an answer that fits in a single reply. A ranking, a hot take, a choice between two things, a silly confession. She can type it without thinking, and then you are talking.

Poor topics need a speech. "Your life goals" and "what you are looking for in a partner" feel like a job interview, and she has to write a paragraph to a man she has not met.

a dating coach's ranking of conversation topics is a useful guide. Topics about her and you, told with some feeling, beat facts and third-party subjects. So choose a topic that lets her say something about herself, such as a food she loves, a fear she has or a habit she is proud of, and not one that asks for general knowledge.

Six answers you can adapt

Food: "The best sandwich in this city. I have a ranking and I will defend it."

A mild fear: "Your most irrational fear. Mine is geese. I will not elaborate."

A choice: "Beach or mountains, and you have to defend the answer. I will be rude about the wrong one."

A confession: "The worst advice you ever took. I have a collection."

A small skill: "The one thing you are weirdly good at. I will go first: I can fold a fitted sheet."

A plan: "Where you would take me for a bad first date, and where for a good one."

Each one is concrete, takes a sentence to answer and shows you have a sense of humor. Each also reveals her personality in her reply, which is what makes the second message easy to write.

Keep it friendly

A bit of attitude helps. "I will defend it" and "I will be rude about the wrong one" are playful, and they invite her to push back. Pushing back is a reply, and a reply is the goal.

The line to watch is the one between teasing and sneering. A dare or a joke aimed at a food, a place or yourself is safe. One aimed at her taste, her job or her looks is not. Words on a screen carry no tone of voice, so the friendly version has to be obvious.

What to stay away from

Do not pick politics, religion, an ex or the news. coach says to avoid current events and politics on dates, because they create the wrong kind of tension. It applies to a chat on an app even more, since you cannot yet read her face.

Do not pick yourself as the topic. "Me" or "my favorite thing about me" tells her you are the subject, and there is nothing for her to say. And do not write "whatever you want." That puts the work back in her hands and cancels the promise in the prompt.

Finally, avoid anything with a right answer she might get wrong. A quiz can feel like a test, and a test is not a flirt.

Be ready when she starts

The prompt is a promise, so keep it. When she writes, answer the topic you named right away, with a real answer and a little story. If you said sandwiches, tell her the one you would defend and where it is.

Then ask her about hers. Give one fact about yourself, ask one question about her and suggest the next step once it is going well. A Saturday coffee near wherever you both like is enough. The prompt got you the first line. What you do with it decides whether it becomes a date.
