Sometimes I take pictures of my feet

That if my memory is generally labile, however, i can return to a place after years just because i saw its location on a map for half a second.

Sometimes I take pictures of my feet to remind myself that I walked, to remind myself that I have walked-in this case I had walked half of Paris-or, even, just to put back in place the proportion between me and the world. To mark in my notebook that I have my feet on the ground.
