his silence is a sign of jealousy

After you worked in a group with your classmates, one of whom was Kevin, Joshua ignored you all day. You try to talk to him, but he is completely silent with an annoyed expression. In the end you get tired and silence him too.

instead of us talking to each other, silence ensued all night. When bedtime came, we were in bed, he slept on the very edge of the bed, avoiding you. You were fine so you tried to sleep, but... The most rare thing happened. When you try to sleep,you are disturbed by the whining and sobbing very softly.

"m-meanie.." He mumbled with a small cry, still with his back to you.*
