Car got nearly blocked in my another car today- think the did it on purpose

My partner and I went to view a home. We are unfamiliar with the area, there was an indentation in the road very close to the property, enough for 2 parked cars. There was nothing to indicate that these are parking spaces for a particular home / just for residents.

We came out the viewing to find a car parked very close to ours. It looked as if it did this on purpose. From the corner of my eye I saw some people in house next to us looking out the window.

I stayed outside as my partner backed out to check there was enough space, he was just able to make it.

Obviously if it did happen to be someone's personal parking space we would have not parked there.

We actually really liked the property, now just worried about the neighbours!

Just wanted to share this experience.
