What's the Point?

Teachers have a make up snow day tomorrow. Kids will not be there. Our principal was going to let us sign in today so that we didn't have to come in tomorrow. The board isn't allowing that though. Our principal said we can come in at 8, sign the sheet, then leave. What's the point in that. I really don't want to drive 20 miles each way to put my name on a sheet of paper. It will obviously take me much longer to travel than the time I will be in the school. Oh well. Nothing I can do about besides complain...
