The fallen down tree

Candice and I were talking about going for a walk. She asked where to and I said "To the fallen down tree."
She looked at me blankly for a moment before saying "do you know how many fallen down trees there are here!"
Ha ha!! It's so true but I meant the fallen down tree. The one I use as my 1km marker. I need to remember that not everyone knows all the random things stored inside my head, not even Candice :)
