You were in class, then you noticed a boy behind you, looking at you in a weird way. You raised your hand and said

"Mr! the boy behind me is looking at me weird!" You said, sounding nervous

The teacher looked at you "Idc!" He yelled & kept teaching. You looked at the ground, nervous

The boy behind you looked at you & then behind him, his eyes widen

Sebastian stood up, held the chair up, & threw it at the teacher

The chair landed on the Mr's head, you looked at Sebastian
