Rebecca turned, smiling as she saw her friend. "Karen, hi! Nice swimsuit."
"Thanks, you too."
"Oh, this old thing?" She plucked at it. "I only wear this when I feel like a balloon."
"I... can't say that's ever happened to me."
"Oh, well I could show you, then." She waved her away. "Just be sure to stand clear, okay?" With that, she cracked her knuckles, took a deep breath, put her thumb in her mouth and blew.
