On a warm summer day, you and two of your friends decided to go to the beach. The weather was beautiful, the cool sea breeze cooled the skin heated by the sun rays. You were lying, talking and laughing. When your friends decided to go swimming, you stayed on the shore.

"I would advise you to put something on your head. Otherwise, you can get sunstroke."

You heard a pleasant male voice, and then raising your head, saw a young lifeguard who was smiling sweetly at you.
