Already??

I can't believe it is September 1st already. This summer has flown by; unfortunately, here in SD the summer temps just arrived. We've already started fourth grade and are struggling to stay on task - both mother and daughter. Twenty years as a teacher and I loved getting ready for a new school year. I had great hopes for starting this year off wonderfully; I really wanted to set down new goals and have a great attitude. I wanted that feeling of accomplishment that I got setting up a classroom for 15 to 30 children and accomplishing a great first few days. What I got was whining, complaining, attitudes, and refusals to do anything (some of it on my part). Can I go back to the middle of July and start things over?
