We have a married UPS driver who is quite the ladies' man and flirts with me regularly.
I found the most fun was first to confront--once he let on he was married, when he
starts up I'll instantly say stuff like, "You are a bad terrible married man."
And when he comes in I just pipe up something like, "Good morning you bad person."
I always just refer to him in some way as "Bad." (Which, on a serious level, he is, but
he's also human...and this is his flaw. He hunts too, which gives me the opportunity
to greet him as "Bambi Murderer.")
And he starts laughing and just takes himself off.
But the flirting is still the water he swims in, and for this weary old fish, it's nice to see
a sparkly grin. Reminds me I used to be a mermaid.
