School starts back on Friday

I had to look up on the county board of education website to find out what day Lexi goes back to school. She goes back this Friday. Why in the world do they resume school on a Friday. Lexi has wanted to go back to school, well pretty much since the day she got out, and now Friday will basically be a tease since then it'll be the weekend. I just don't get it. School started this year on a Thursday or Friday as well, and I thought it was dumb then too!
Granted, I'm glad she gets to go back...she gets so bored at home and wants to see her friends, but still Friday?!??!
