You know it is really hot... when you do all you can to HIDE from the sun... When you prefer to be inside even when the weather is lovely... When you start sweating just putting your nose outside the door. When you don't even wanna think about food but wanna eat icecream and drink fruit cocktails all the time. When everyone's tanned and walks around in small and light clothes.
That's when you know the real summer is here! And I'm in Italy! And I love it!
