You were sad today, and your friend noticed it. While the teacher was turning away and writing something on the blackboard, she turned to you. You're looking at her. Her display flashed "U good?". You shrugged your shoulders. On her display is a new inscription "Talk later?". Your display read "It's sucks pretty hard..". She thought for a while, and then she smiled sweetly at you and her display flashed ">:3". You felt a little better and you smiled a little.
