I saw Trevor sneak up the stairs where he went into his room and closed the door.
I waited about 20 seconds before calling his name.
He didn't answer.
I called again.
Still no answer.
So I went up to check and discover him with my teacher box which holds assorted highlighters, pens and pencils.
He jumps to shove something in and closes it.
I say, "Hand it over, Punk Face".
He says, "I LIKE PINK!"
And sure enough...he now has a pink highlighter stripe running along his bedroom wall.
