Is her Mum being unreasonable?

Well, W0W!..lol!..haha..i'm sorry but this is so ...strange and unreasonable..not only that it's crazy O_O..I really can't understand why this mother's being so strict...If my mother did this to me, well i don't know i would ask her why..You could ask your friend why but if doesn't tell you maybe something's wrong in their house :/...mm..
