My "friend" was back this morning. I think, but I'm not sure. I thought the van was brown with brown stripes but the van that drove past me (3 times!) this morning was blue with blue stripes. Other than that, it was the same shape, style, etc...So the behavior's the same, but I really thought it was a brown van. And I didn't get a good look at the man the times I've seen him before, but I had the feeling the guy was more middle age. This guy was younger. 

So are there two weirdos driving around my neighborhood in the same type, but different color, van or is my memory just that unreliable? This time I got the license plate, but now I don't know what to do with it. What if this guy was just lost in the neighborhood or something?
