Visiting the bouquinistes along the Seine and going through piles of books
Gazing at the rooftops
Wandering the streets of Paris
Listening to the street musicians
Sigh. I'm not fussy - any one of these ideas would work for me! Dreaming of Paris at least stops me from thinking about the heat. I suppose concentrating on snow and winter would be better, but not so much fun.
Hope you get some breezes soon!
