What is your Thumb Doing on my Face?

This is my buddy, Beata.  You might remember her as the guitar player from the band I was in just before I quit my job to travel the world.  (Ramona Day.  We were awesome.  Click here to sample a song.  *cough*).  Anyway, this is an extreme close up of a spot on her face.  Right before this photo was taken, and just before we rolled around on the floor laughing hysterically, I stuck out my thumb and tried to rub out the spot, saying, "you have something on your face."

And she said, "that's a sun spot.  And thanks for wiping OFF the foundation I put there to try and cover it up."
