Before my children learned to speak their mother tongue, they used sign language to communicate with others. Their vocabulary was limited to: please, thank you, more, and I’m sorry. If those four words become the limits of our vocabulary, will that be enough? Well, those 4 words and the word for coffee. Coffee is a given, right? Oh, and wine, and beer. Shoot, I think I just answered my own question. I will need to get a Portuguese dictionary of libations and other useful phrases.
