Acho que o Goldenoldie apenas conseguiu entender que estavam falando português e com isso ele usou o Tradutor Google. (Em Português)
I think that Goldenoldie only get understand that were talking portuguese and with this he used the Google Translator. (On English)
You are partly right. I know quite a bit of Spanish, and Portuguese is similar in a lot of ways, so I can understand perhaps a quarter to half of what you guys are saying without using Google. Of course I needed to use Google to reply!
For example I understood perfectly the post from dannyrafter without using Google, and my reply is thank you for the invitation, but I am sorry I am too busy.
