Used car saleman?

Today I had oddest experience and I'm still processing it. Ok, fine I make jewelry and other crafty things, I sell at craft fairs, roller derby and on Etsy, I even had my stuff in a store last year. But today I had a meeting with a woman who just opened the cutest store in my neighborhood. Not thinking that I was an actual vendor or salesman, I walked in with my case full of jewelry and bag of tshirts and onesies. I took each item out and gave an explanation of what I was thinking when I made the item. The whole time I was doing this, I felt so uncomfortable. Uncomfortable with what I'm not sure, the idea that I was putting my whole creativeness out there for the world to see? Afraid that they, general public whom I don't know, would be judging?
