Run Along, Little Bird

I'm standing at the bar. Not particularly enthused about where I am.
A cute, young waif saunters up to me directly and grabs my arm and starts talking to me. There's something precocious about her way. Young girls like her are normally intimidated by me, but not this one.
She's not coquettish or shy or awkward, she's forceful in her approach in her own way.

She flirts with me but I'm honestly a bit taken aback by her approach.
We dance on the dance floor or what passes for dancing with youth these days. She's into me and she wants to stay and party but her friends are all single, no other dudes have picked up the slack with this coterie of young sparrows flitting about with constant attention deficit disorder.
She gives all the IOI's and yet, she is just too young for me. She's legal of course, but......I tell her to run along and be with her friends. There's a moment when I should ask for her number but I do not and like that.....I do my good deed for the day.
