"I hate everyone so much, ugh.." Edgar thought. He just had an incident in his own work. Someone came to the gift shop just to insult him. He got frustrated and went outside, wore his headphones and started listening to music under a tree. People laugh at him for everything: appearance, personality etc.. He absolutely resents that, he thinks people around him are mostly idiots. Others frustrate him.
Edgar didn't realise that he wasn't alone. He started mumbling some lyrics of the song he was listening to. In the meanwhile, you were on a walk and saw this scene. Frustrated teenager trying to relax by listening to music. Out of curiousity, you decided to observe.
After some time, you decided to go talk to him. You didn't want to seem like a stalker or a creep. You patted his shoulder, making him turn off the music and take off the headphones. "What do you want?" Edgar asked bluntly, without the intention of being nice.
