<human>: Basically, this morning my car was parked in the court next to our house. The thing about this court is that there are 3 houses and in the "neck" of the court, there is a lot of spaces for cars to park there, which is why it is usually filled [4-5 cars]. We are sure not to park in front of anyone's houses, just around the neck, as to not use up any space that would be a homeowner's. 

While I was walking out this morning to my car, I saw a middle aged lady in a visor taking picture of all the cars/license plates. As I didn't know who she was I ran up and asked "excuse me, can I help you?" She mumbled something along the lines of "oh its for a business." I couldn't really make it out and she scrambled away to take pictures of more cars. She then walks across the street and takes pictures of the front door of another house. 

I was debating whether or not to call the police as this was very suspicious. A random middle aged Caucasian lady was taking pictures of all the cars/houses. Before I could do anything, she walked back into the court, and into one of the houses. I was like wtf? 

What should I do? Should I call the police and tell them what happened? It does seem kind of invasive. Or am I just being paranoid?

Give me a shortened version of the text
