There was a lovely older teacher that used to do substitute teaching in our school a few years ago. One day she came to school in two different shoes. Nothing ever phased her and she just passed it off by saying
"Girls, just you wait 'til you reach a certain stage of your life and your brain turns to mush because of a hot flush, then you'll think of me".
I thought of her again today when I arrived into school and Mr Potterton kindly drew my attention to my feet.
I'd like to say that it was because of the dark morning and I couldn't see properly. And in my defense they were both the same height so I had no reason to look down.
I tried to pass it off to my class as a fashion statement, but no luck!
