It was on the ride back from a summer program I'm doing. I was sitting next to this girl who was probably around my age, maybe a year younger. She was half awake from the time we got picked up to the time she got off (I was last). She was repeatedly dozing off and laying her head on my arm. She apologized for it, but I didn't mind that she was doing that. I then told her: "You can rest your head on my shoulder if you want, you seem really tired." She then replied: "Thanks," And rested her head until she had to get off. she said thanks again before walking into her house.
