Let's debate.  Would it be creepy for a guy like me to connect with a woman over Linkedin who I worked with approximately ten years ago, when I worked as a delivery boy, and she worked as a hostess, at an Asian restaurant?  At the time, she was a high school student, and she would flirt with me in unusual ways, like tripping me and pretending it was an accident.  Of course I ignored those advances, considering she was in high school and I was around the age of 24....

Now she graduated it seems, and she works as a software engineer.
