Schedule?

got my schedule around 8:30 this morning. My first class was at 10:20, AND I see the same class first period tomorrow! Yikes! That means a different lesson plan for in the morning! but Wait! My supernatural source is in control! Some kind of announcements/ceremony during the 10 mins between class so the class did not start on time. I only had 15 minutes to teach! What does that mean???? No new lesson plan needed! Will finish up the first one tomorrow! Thank you, thank you, thank you!!!!!
