Planet Mad

In the department we have a system of observations set up so we all visit another teacher and watch one of their lessons. I had a colleague in my Upper Sixth lesson this morning, and we were talking about strategic planning for businesses, using McDonald's strategic direction mapping technique: all very exciting stuff, as you can well imagine. I decided to use supermarkets for my example. Just imagine the scene: the outline map is projected on the board; I'm taking each supermarket in turn and marking it in the appropriate position on the map; I'm waving my arms round energetically; it's all going really well. And then my braincell explodes. I get confused and forget how to speak. I refer to Lidl and Aldi as "Addl". Bugger.
