You can't remember the last time you wore socks.The days have imperceptibly become a little shorter, you find yourself surprised to see that it's only 7 or 8 o'clock when the sun is descending and the shadows are long. Some evenings you even consider pulling out a light sweatshirt because the air is cooling down more quickly each night. Even though in your mind it was just June, you realize that summer is waning all too fast.
