Secret Admirer

This afternoon, even though I left the office early, I was the last one out the door. When I got to my car there was a rose on the windshield, tucked under the wiper blade. Do I have a stalker? A secret admirer? My office is in the middle of an industrial park so it's not like there is a florist on every corner. Very strange. And just a little creepy. I brought it home anyway because it seemed not right to just toss it on the ground.
