Strange car parked across the street for an hour???

Okay so normally I would say whatever but this car has been parked across the street for over an hour, they have not turned off the car or lights or gotten out.. they are literally just sitting in their car.

We live in a really sketchy neighborhood and there has been a lot of robberies in the last week. I've made it clear I'm home by switching on the porch light and everything but other than that I have no other way to protect myself being home alone. I think I'm just being paranoid but it doesn't seem like normal behavior especially for the middle of the night. And there are no houses across the street 😐

Uhggg I will not go to bed till they leave, it's times like this that I wish I had a dog. I hate my anxiety at times like this 😟
