You are walking to school alone looking down. And you hit somebody's back and you fell. You looked up to see who was in front of you and there were two twin boys looking at you. You bumped into Angry's back.

Angry: "The hell?!" Angry said with an angry tone like his angry face.

Smiley: "Look ahead when you are walking." Smiley said with a grin on his face. His eyes were close.
