Psycho/Psychic

Handing out stickers to my string ensemble students.  The next girl's folder has green and silver stars around the name tag, with silver at either end.
9-yr-old girl: Could I... please... have.... ummm...
Me: ...a green star?
9-yr-old, indignantly: How did you know that?! You're not psycho!
Me, laughing: Ah - do you mean psychic...?
9-yr-old, startled: Oh!  Yes.  Sorry.
