WALKING DOWN THE SIDEWALK

I'm not sure who invented the sidewalk, but I'm thankful for the use of a sidewalk.  Walking on the side of the road is dangerous.  Walking on a sidewalk on the side of the road is far better.  According to research, Ancient Greece and Ancient Rome built sidewalks only to fall out of use in the Medieval era.  Then the Great Fire of London in 1666 brought sidewalks back into use.  Sidewalks have been built from wood, brick, stone, concrete and asphalt.  I'm not picky what material the sidewalk is made from as long as the sidewalk is sturdy and functional.
And as I'm lost in thought in the Summertime, here are some photos of Lea Seydoux and Adele Exarchopoulos.
