Quit whining and calm down. It's hardly unusual for a student to miss the first day of school- it happens all the time, All you need to do is say that you were on vacation or something, or that you misread the calendar. Not a big deal. As for the Mac, all you need to do is format it so you can use it- which means doing things like entering your name and passwords. Again, no big deal. And if you're in high school, then you are nearly old enough to drive and have a license of your own. YOU should be responsible enough now to make sure that you get your needed school supplies long before school starts. If that means you have to take the bus over to the local Walmart for some school shopping, so be it. There are worse things than that. Getting school supplies isn't your mom's responsibility, not anymore. It's YOUR responsibility now. Part of growing up, pal, is learning how to take responsibility for your own life.
