Onomatopoeia

This morning, Anna waved her magic wand (a hanger) at my window. "Pshwsh! That makes it disappear," she said. She swirled the wand again, "Pshwsh! That makes it reappear."

Sarah grabbed a magic wand (also a hanger) of her own. "Can I Pshwsh?"

Anna: "Sure! You can do the doors."

Sarah: "Pshwsh! Wow!"

Anna aimed her wand at Sarah, "Pshwsh!"

Sarah: "Hey! Don't Pshwsh me! I don't want to be Pshwshed!"

Anna: "Pshwsh! There. I reappeared you."

Sarah: "Thanks."
