text: People sometime forget a book or a binder in their classes. When this happens they need to go around and try and find. Trying to find a textbook in a large school is hard. If your friend is in Math and finds your book, would it be a problem if they text you saying I found you book. This will take the stress off of the kid who lost the book. It will all be done before class, so it won't disturb anyone. But if phones aren't allowed in school kids couldn't do this. This can cause many stressful students who can't find their textbook.
