Would "Where do we go on Wednesday?" work here?
These days of the week, man. I get it, but was there nothing better available?
That's exactly how I feel.
Why "onde" instead of "aonde"?
All of these days of the week hurt my head. :(
You don't need to speak "feira". In Brasil rarely we speak it.
i confused as to how this is the future. isn't going = indo? or maybe vamos ir, right?
That sentence is the most usual in Portuguese. "Estamos indo" would express a present situation, not future. Although many may use "vamos ir", it is not considered "polite" to use the verb ir twice.
