Could be, pedalpete. I find people are generally positive and encouraging, certainly polite. It can be difficult, even a little uncomfortable when face-to-face, to try and visualize another person's idea. People will grasp at tangible analogs as a way to understand a new idea, which can be tough to stomach as an entrepreneur when you clearly see a unique vision. No one is ever as excited about the idea as the entrepreneur... or else something is wrong!
