Brainstorming

My view on brainstorming is that everything is allowed. Today I learned that not everything is. Words like no, not possible, ain't never gonna work and the likes are not allowed in a brainstorming session.

I made an ass out of you and me (assume), that this was not allowed, but didn't have the ability to phrase it. Even if I knew that before, I now also have the ability to put it in words.

Again, isn't it great? You learn something new every day.
