"Look what you did!"
Translation:Regarde ce que tu as fait !
I don't understand why you would use "regarde" as opposed to "regardes" since I am speaking to "you."
But when you say "Put on your hat, my son" you would use the "tu" conjugation (Mets ton chapeau, mon fils)... the imperative confuses me
Having trouble with this as well. Best I can tell it has to do with whether the verb is an -er or -re verb. In this case, regarder vs. mettre.
