I have taught many an in-service workshop in my day but one really sticks out in my mind. I worked really hard to put together a workshop on integrating writing into all subject areas. My audience appeared very enthusiastic and before I knew it, it was time for a lunch break.
All the teachers were back in their seats and ready to continue after lunch. I showed lots of examples and gave each teacher a notebook I had put together for them. When the workshop ended, I felt that they had been a really receptive audience. They applauded and several came up to thank me for my presentation.
I began putting my materials away when one more teacher approached me. I smiled, waiting for another positive comment, and looked her way. "Did you know that you have a piece of spinach wedged between your top front teeth" she asked. Sure I did. I ALWAYS get up in front of fifty teachers with a green leaf stuck right where I can show it off. I replied that I didn't and thanked her for telling me.
I ran for the nearest restroom and yuck! She was right! Why couldn't they have told me sooner!
Lesson learned: always check your smile after lunch when you are doing a presentation. I learned the hard way!
