in the maghic brocade the mother is very  tenacious by nature  because she order to 3 sons to take her brocade so i think the mother is a little bad and the first and second son is bad to because he didn't take his mother brocade and  they run away with the money and the last son is a kind because he go to  the difficult way but the last son doesn't give up and go to the fairys house and take his motheres brocade and have a big house and he have lot of money so he ahve a luck i think
