Which do you use more, "nós" or "a gente"? I have learned that in Portuguese you can either use "nós" or "a gente" as a subject pronoun for "we", but which is used more? Do you use them in different situations? Is one more formal? Is "a gente" easier to use because you don't have to conjugate the verb into the 1st person plural form? Is it the same to say "Nós queremos falar português" y "A gente quer falar português"?

What is the difference between "Eu te vi" and "Eu vi você"? Do you use different direct object pronouns in different situations, or are they interchangable? Is one less formal? Is one used more than the other?
