Scaramouche

Scara, Xiao and you were best friends.

The three of them sat next to the window, first Xiao, then you, and in the last seat, Scara.

One day, in a tedious and boring class, Scara handed you a folded piece of paper. You didn't pay much attention to her, but a few seconds later she gave you another piece of paper, this time stretched out, that said "read the paper>:o."

You stretched out the paper and read it

What was she saying?
