you were at home with Dylan, arguing with him, all over Because of how fed up you are with how he treats you, and the fact that he doesn't give you any attention anymore. your anger slowly heated up and you yelled "I'm leaving then!", and with an angry face he yelled back

Dylan: fine! Leave then. The doors right behind you! you turn around to leave, but when you turn around, the door is all boarded up, giving you no chance of leaving...he chuckles you think I would just let you leave?
