"Oh! Geez." She grimaced a bit of a smile at the poor guy. "Sorry. Didn't mean to pop right up in your dance space there." She chuckled apologetically and shrugged. "But yeah. I'm real. Hi."
She gave a meek kind of wave and hoped she wasn't about to get punched because that would just be her luck. Thankfully she wasn't in costume so no fishnets and top hat to immediately get her arrested for being an outlaw.
