Hello to everyone, my name is Larissa and I'm here to help in the portuguese BR books.
Thank you a lot! I hope I can help!
Hello // Olá --- Brazil
Oooh, brilliant, nice to have you here, Larissa. There are lots of wonderful old books to work on in BR Portuguese! Please do just ask if you have any questions. And have fun! 
There's honestly no such thing as a stupid question -- but I'm afraid I can't rule out giving a stupid answer : : To Posterity and Beyond!
