Me and my brother finally got our mother to do it. We went home and start to talk to her that she could earn some money without leaving the house. We've tried several times before but she never agreed, this time it was diferent, she (and us too) wanted to buy a new car and this made all the diference. She started to think on the new car and in no time me, my brother and our mother were working hard to have the money to buy it.
