Reflection:
From this exercise, I reinforced my understanding of formal commands in Spanish. In particular, I learned the difference between affirmative and negative commands and the rules of conjugation for verbs addressing an individual formally (Usted). I also practiced spelling some verbs correctly in their command forms, which helped me become more confident in using commands in conversational Spanish.
