Do you ever ask someone, "How are ya?" and they respond with, "It's Friday!" as if the previous four days were some sort of torturous journey?
I like a good weekend too, but I believe we need to set up our schools to be desirable every day of the week! Fridays should be no better than any other day. Wednesdays shouldn't be half-way though the grind of a work week.
Mondays should sound like, "Oh my goodness, it is great to see y'all! I am ready for a great week! I hope you are too!"
