"Nós falamos sobre nossas vidas."

Translation: We spoke about our lives.

[jayeless]

I haven't even done any "past tense" lessons yet... isn't the -amos ending for both present and past tenses?

[erudis]

Yes, it could be "we speak" too.

[olyglotED]

The same rule applies in Spanish as well.

[FabTapp]

-amos is to indicate plural. The past tense would be falávamos (so "-ávamos").

[punkdoabc]

"-ávamos" is a past continuous, while "-amos" is eighter present or simple past.

[Paulenrique]

"Falamos" can be either present or past tense.

• Nós falamos inglês = we speak English
• Nós falamos com você ontem = we spoke to you yesterday
• Nós falávamos sobre carros = we used to speak (or "spoke" or "were speaking") about cars.

[WaynK8]

When written in the simple past, shouldn't it include an accent mark as in "falámos"?

[Paulenrique]

This is the case for PT-PT. For PT-BR, the it is the same.
