The mysterious humming noise and the light coming from the living room are keeping the young protagonist of this story awake. To understand what is going on, she reaches the room where her mother is and realizes that she's busy sewing protective masks. She also finds out that from now on all essential workers and all those who have to commute to go to work, must wear a mask. Once the young lady's reluctance is won, and she resolves to wear a colorful mask made by her mother, she asks her to teach her how to sew. She wants to make a mask for her grandfather, who, touched by her gesture, hugs her tight as he walks in after his tiring shift at the hospital.
