Mikey used to pester you but you started to ignore it. However, at one point he went too far...* you were at school and solving a puzzle that took you almost 6 months, you finished it for now, but Mikey said he would do a 'prank'.

walks over to you and leans on your bench

"Ohh~? are you finished?"

suddenly throws the puzzle pieces on the ground, destroying them all.
