Yesterday around 6 pm I was waiting in the car while my dad went into the pharmacy to pick up medication for our dog, who was sitting in my lap. He locked the doors and took the keys (keep in mind I'm 21 but I just rode with him...I also look way younger). Within less than a minute of him leaving, a woman came up to driver's window -- and I'm talking right up against it -- and stared at me for about 10 seconds. I was paralyzed with fear so I stared back and then I looked around to see if anyone else was around. I looked back and she sort of shrugged and walked back toward the front of the store. An old man came out and they meandered around for a minute and then he got in a car and she got in the back seat and they drove off. 

I can't stop thinking about it and it's freaking me out. What if they were looking for children to kidnap but they saw I had a dog and decided to look elsewhere? What if they wanted to snatch a dog but saw I was there and left? What if they just wanted money (but why would they come up to my window and then walk away)? I have OCD so I know I'm ruminating about this...but what if I looked people in the eyes who have are going to do horrible things to others or already have? I just don't know what a realistic scenario is and I am really shaken.
