So, I went out to my car today to find this note: (keep in mind, we share a two car garage and two car driveway with our neighbors)

Dear Neighbor,
You do know where we live, if we accidentally park too close, we could have moved. Besides, I would hate to dent your new van because I was trying to get into my car.
Thanks,
XXXXXXXX

Well, obviously I was able to get in and out of my car. If I wasn't, I would have gone to their house and asked them to move their car. I feel like leaving a note saying something like this on their car:

Dear Neighbor,
You do know where we live. If you accidentally parked too close, we could have moved. Besides, I would hate to charge you with a dent in my new van because you were trying to get into your car.
Thanks,
Katie

However, I'm refraining and will, from now on, knock on their door when I get home at two in the morning and ask them to move their car.
