Was followed in car after taking a picture

Was driving and was behind a pickup truck. While at a red light the little sliding bed window opened up and a kid maybe 10-12 or so stuck his head out and started making funny faces at all the cars. Always having a camera in the cup holder I took a frame. We both pulled into the same Home Depot. Forgot about it the second after the film advanced to the next frame. Went inside, got what I needed and left (maybe 15 mins tops).

A few blocks away from the Home Depot I noticed the same pick up truck behind me. They followed me for a bit so I started making odd turns that kinda went nowhere. Like they would make no sense if you had a genuine destination in that neighborhood. This went on for easily 10-15 mins. I never sped up or made any attempts to “shake them”. Kept it normal. They continued to follow. Got the sense they wanted to see where I lived. Eventually I passed a double parked car that they couldn’t easily pass and it was down a street with multiple turn offs. I doubled back and drove around for a few minutes before going home.

Anyone ever have anything like this happen to them? Been taking photos for 30 years. This is a first.
