Yup! I didn't understand what the term boundaries even meant until a few years ago. But now I realize boundaries are a tool than can help both people even if they don't know it yet.
I am a think outside the box person, (sometimes creative), an idea guy or dreamer if you like. I think that becomes an easy target. If you are miserable and insecure, nothing is more fun than popping other people's dreams. I will also admit I'm not immune to this behavior too but I'll stop here before it gets too personal :)
