It depends on the salon, 10~30 reais, I live in Brazil.

Indeed. I have noticed it while "reading" (I am too bad, shoshinsha desu) natives' content, watching movies, anime, playing video games.

I use English whenever I can, it does make part of my life. I could say I learned English by using it, I have never read a text book, but I am better at listening and reading as I don't have many chances to speak it.
Now I am doing it with Japanese. Creating an artificial immersion is important because it makes your brain familiar to the language.

A relationship needs time, but for sure I would like to know him/her.

Thank you. 

So you know the song. :)

I like that band, but I prefer Usagi. Do you know that one? They have a similar sound, but there is something weird about Usagi.

If you don't mind it to be Brazilian Portuguese, I can help you.
