Indeed. Suppose my mother got a wage of R$1250,00 (that's what she get every month. My Dad (that does not live with us) send to me €$500,00 (that's like, R$1000,00 here) ) and i got R$1000,00 every month, then, we have "just" R$2250,00 to pay, our house, bills, and other things.
The life here is way expensive. People tend to think that Brazil is an easy place to live, but it's not. If you're not rich, this place is just a hell.
