When talking about past actions, most verbs use avoir, but there are a few verbs that use être: you use être with verbs that express movement, change, or states of being.
You will also use être with verbs that start with se, like se réveiller, se perdre, and s’habiller.
Ils se sont perdus.
They got lost.
Nous nous sommes habillés.
We got dressed.
When you use these verbs in a sentence with ne...pas, you will have the following order:
Ils ne se sont pas perdus.
They did not get lost.
Nous ne nous sommes pas habillés.
We did not get dressed.
We already know that in French spoken language, we can use expressions differently than in written language. For example, sometimes we don’t use ne: people will say j’ai pas instead of je n’ai pas. You can also use a different word that means the same thing. For example, in spoken French, people say boulot, and in written French, they use travail, although they both have the same meaning, work.
J’ai beaucoup de boulot aujourd’hui.
I have a lot of work today.
Mon boulot n’est pas intéressant.
My work is not interesting.
Je vais au boulot.
I’m going to work.
