I walked up to a friend this morning, she was giving me a lift to a coffee morning with friends. She was weeding her front garden. She rushed in to fetch her car keys, we drove off and she suddenly turned round, saying 'Shoes! I forgot, I am wearing my gardening crocs!' I looked down and she was wearing a pale pink pair. I immediately thought of this thread.
So she went in and changed into her smarter shoes, and blow me down, they were a newer (therefore smarter?) pair of pale green crocs...
