My mom bought me pencils from the dollar tree the erasers are extremely hard and I can't erase anything with them I have to use eraser caps and she refuses to buy me name brand pencils and when I try to use my own money to buy pencils but she always yells at me and tells me not to buy them nobody else can drive me to the store and she won't allow me to walk on my own so how do I either soften the erasers on the cheap pencils or how do I behind my moms back buy pencils?
