Or what? I've parked my car at the school parking lot at 9am. After the classes were over at 4pm I walked over to my car, sat in the driver seat and...saw four! large bird hmmm...excrements on my windshield. :) I'd like to note that there are no trees around whatsoever, just a plain huge parking lot. I got out of the car just to see if the cars next to mine had any on them - NOT A TINY DROP! It's a mystery, so I just took it for a Good Luck sign from God. :) Thank you birdies, drop by anytime.

Upd. It dawned on me that this could be an act of vengeance. :) My cat somehow keeps catching birds on the 2nd floor porch with 12 foot high ceiling. I don't know how he gets them, I don't think he's that fast and I've never seen him up in the air. :) He doesn't kill them, brings them inside and plays with them, and he's got about 5 birds within a couple of months. 4 of those were cought later by me and set free, but the last one somehow drowned in a vase with flowers when I was out of town for a weekend. It's been a sad experience and I ask for forgiveness. The cat has been warned and punished. :)
