Have you ever had that happen when you are away from your area by several hundred miles and you see someone who resembles someone you know back home? But you know it cannot be that person?
Or in the alternative, several years ago - I was back in my hometown where I still have some family members, but my wife and I live 3+ hours away. We were making a LATE night trip to the local Walmart (we unexpectedly needed to try and find a smaller car seat for our daughter before going off the next day for a vacation with my parents). My wife and I went in and then I doubled back to get a shopping cart while she continued to walk to the baby section. It turned out that my cousin and her husband were also doing some late night shopping. They saw my wife, but because I wasn't with her, they weren't sure that it was her... Since they didn't expect to see her there, past 10:00 at night, alone, etc...
Very much like Gerianne narrated, my cousin said to herself: "I know her. That looks like Linda. Could that be Linda?" Doubting to herself that it was she still approached my wife and carefully asked her: "Linda?" LOL! I came walking up to them a few minutes later with a shopping cart and we probably talked for 20 minutes!
