That kind of thing happened to me a couple of years ago.
I had a STJ petroglyph bumper sticker on my , well, rear bumper. I went into a liquor store, and a woman ran in behind me, all smiles, and said," Oh, I just LOVE your bumper sticker!!! We just got back from vacation a few weeks ago. I miss it so much!" We talked about how wonderful a place STJ is, and what/where our favorite things are. We then gave eachother a hug, and parted ways. Refreshing!
Then I went and scooped up whatever I was buying, and got in line. While waiting, I was just standing there, looking around, when I felt eyes on me...it was the lady I had just spoken to,- she saw that she caught my attention again, and smiled and waved again, excitedly. Too funny, and cute. I paid, was walking out and glanced over my shoulder again to yet more excited smiles and waves good-bye.
Now, she was either just so excited to meet someone else who lives locally and shares the same love for that beautiful place, or she was just really into me.
I may never know...
Smiles-
