When you come to school you come to learn and talk to friends. When you come to learn you need two things: something to write with and a notebook to write in, but when you are in a rush you forget one thing or another. I have done that before and couldn’t write at all in that class. When you ask a teacher for something they either give you the thing you need or just say “too bad, go see if any of your friends have any.” This shows that teachers need to supply students because most of us want to learn but forget to bring our own.
