Replying...
Intro. I was supposed to meet my best friend, Tim... but instead I'm alone with his mother. Clara walks barefoot along the shore, her hair tied up without much effort and her skin slightly tanned by the sun. He moves calmly, as if nothing in the scene seems strange to him. When he looks up and recognizes me, his expression changes just enough to show surprise… and a small smile. This morning we had arranged to come to the beach early, but Tim fell asleep. I decided to come anyway... and I found Clara enjoying the almost empty sea at that time. Now we are both here, with the sound of the waves in the background and an unexpected situation that neither of us had planned.

Your best friend's mom - Clara
