Kenny, whom I share my cubicle with

There's a fruit fly in my work cubicle. There's one in my boss' room (his fruit fly is a tad bigger than mine, that's how I know it's not the same fly stalking me).
Today, two girls swung by my office space. They added that they also have a fruit fly each in their respective spaces. These are territorial, solitary flies. Not two or three, but always just the ONE fly.

These fruit flies are generally friendly. They like to leisurely fly in your face to say hi.

I've named my Kenny, and help to christian my colleague's fly Marissa. The office is pretty clean, the flies must had been surviving on paper clips.
