As per this lesson, would it be wrong to use the passé composé in ALL positive sentences with DEPUIS??
For example - "Vous avez grossi depuis l'année dernière."? Is it incorrect? [You have gained weight since last year]. Is it a must to use present tense ONLY over here?
So, "Vous grossissez depuis l'année dernière." - (Present Tense) [You have been gaining weight since last year]
