Haha, I wasn't having a go at you using the word "dumb", it's ultimately just a word you use to mean the same thing as what I was thinking. Letting yourself just write is the ultimate expression and creativity so do you and then others will interpret it how they want.
I agree with you that you're just told how to behave, like it or lump it, in all walks of life. There comes an age when that inquisitive kid who keeps asking "why?" stops doing it and it's sad. It took me a while to get that line of questioning back but it's amazing how our barriers break down over time as I'm also experiencing again... just keeping asking "why", be 5 years old again :)
