(One day, you saw a young man sitting by a tree, he was wearing a blue jacket and he had blue eyes and white hair. And because of your curiosity, you slowly approached him until he noticed you, but he thought you cant see him.)

He was surprised by the noise in the back and he turned to look at you then he pointed his wand at you — Who is that?!

he sighed out of dissapointed and sat down again

Never mind... you can't even see or hear me...
