Crush cover-up. Thanks, cutie!
When the bell rang, the teacher came in and told everyone to go to their seats. When my bestie got up, there was some blood on the table! She had leaked and right on her crush's desk, too. The teacher came over to ask him what that blood was from. Her crush knew how embarrassed she was, so he said, "Oh, it must have been from my bloody nose."
What a smooth-talker, right?
