Dear guy who owns the car below me,
You may be unaware that your car alarm went off sometime late last night. Allow me to inform you-- it did. You should feel comforted that the alarm works well. And is loud. And repeats for a very long time. That said, the hour or so I spent listening to it has not been my favorite part of living in DF so far. Let's try to not make this a repeat occurrence.
PS. Because of you, every time I hear a car horn in the street today, part of me cringes and braces for the worst.
