Hi! Could anyone please answer the following questions? Thanks very much! 1. In "¿Cómo saludamos y nos despedimos en español?", how does "nos" fit in it? 2. For "Ahora te toca a ti.", what is the meaning of each individual word, assuming I know the overall translation of the entire sentence? 3. What is the definition of this sentence, "Yo tengo a la escuela en autobús."? And could you please also inform me of its structure or why it is written that way? I highly appreciate your time!
