Let me explain:

So I was driving through the neighborhood to go meet my girlfriend and as I passed this house, two young kids (9-10 years old) decided to throw a rock at my car. 

When the rock hit my car, I laid my hand on the horn for a good 15 seconds, and out of rage I backed up really fast and accidentally hit their mailbox. 

It tilted the mailbox post maybe 45 degrees but looked fixable so I decided not to knock on the door to let the owners know. AITA?
