Whoever wrote this note is my new hero! It says:

“Thank you for waking me up this morning! 🙂 Perhaps you could park your sensitive car alarm elsewhere? I’m not sure how many time I have to call 311 and give them your plate # before they’ll tow [*your ass away] but I’m gonna find out. xox

P.S. you rock!”

* This is my guess at what the note says in the part that is obscured by the windshield wipers.

Thanks to Greg Solometo for the Image!
