New here? This is lesson 190 of a free 240-lesson French course.
Change the subject in French
Inès is mid-story about a night shift when Sam jumps in. He needs to mention the Lyon tickets before he forgets.
You'll learn how to bring up another topic: by the way, that reminds me, before I forget, and a clear let's change the subject.
These lines let you switch threads with a friend without sounding rude. Inès will lose her punchline anyway.
By the end of this lesson
Bring up another topic.

Scene — a night-shift story
Same corner of Café des Tilleuls, late morning. Inès still has her denim jacket on after a night shift. Sam's backpack sits on the extra chair.
The window table keeps its blank brass sign. Gaspard is at the next table on two chairs, café crème untouched, not in this talk.

Learn — another topic
Six lines help you open a new thread: by the way, that reminds me, before I forget, and a frank change of subject.
You'll also get a softer off-topic line and a way to ask a question you meant to ask.

Au fait, ___.
By the way, ___.
When to use it: Slip this in when another matter pops up in the middle of a chat.
Au fait flags a switch, then you add what the new point is.
Say it: The t in fait is silent.

Tiens, ça me fait penser : ___.
That reminds me: ___.
When to use it: Use this when something just said brings a new thought.
This line ties the new point to the last thing you heard.
Say it: The s in Tiens is silent.

Avant que j'oublie, je te le dis.
Before I forget, let me tell you.
When to use it: Say this when you must pass on a thing before it slips.
J'oublie stays one piece after que; then you say the thing itself.

On change de sujet.
Let's change the subject.
When to use it: Use this when you want to leave the current thread on purpose.
On here means we, the way friends talk in a café.

C'est un peu hors sujet, mais j'y pense.
This is a bit off topic, but it just struck me.
When to use it: Use this when you know the new point is not the current thread.
Mais lets you add the off-topic thought after you admit it.
Say it: In C'est un, the t links into un.

Je voulais te poser une question.
I wanted to ask you something.
When to use it: Use this with a friend when a question has been sitting with you.
Voulais points to a question you already had in mind.
Story — she loses the ending
Inès is still on last night's shift when Sam cuts in about Lyon. Watch the topic jump, then the punchline vanish.

InèsOui. Tiens, ça me fait penser : vendredi après le boulot.Yes. That reminds me: Friday after work.- She opens her mouth to finish the hospital story, then stops.
