Wait... I was a teacher?

A former student of mine had the audacity to mock me on a certain social website just now. She implied very strongly that I was lazy when I graded students' assignments, because they would write ridiculous things on them and I wouldn't catch them. This irks me for two reasons, really:

1. I poured my heart and soul into that job. I cared deeply for those students.

2. She was right, after a fashion.

I'm realizing that there are certain aspects of teaching 6th graders at which I was simply not skilled, despite working hard to overcome these deficiencies. I lost patience often, I wasn't as vigilant as I should have been in grading, I didn't always come up with the most effective or imaginative lesson plans, I missed countless opportunities to demonstrate Christ to students and to love them well... Maybe I had to come through it and look at it from hindsight to see it properly. Regardless, I intend to learn from the experience now, even as I sought to learn from it then. But why did I have to hear about it from some disrespectful, incredibly insightful punk kid?
