Is it Sad?

Is it sad that I didn't feel sad at all when my kids left today? There was literally only one student that I will genuinely miss. I will miss a few other well-behaved ones, but not many. I'm not sure if it's because I only had the students for half a year or if it's because their behavior was so bad, or if it's because I had a pretty bad experience at my school. Either way, as you know, I'm extremely excited for a new beginning next school year. Next Friday when I am officially done at my current school, I will write a much longer reflection of my school year.
