:: 290806 :: This (refer to metal gate) is what humans call a Mental Block. It's nothing much of a barricade, coz we just need to push a little with our noses and it'd come down easy. And we'd be free! See, main gate is open!! But, it's also a Sound Barrier. Because we don't wanna have it falling down, because metal crashing sounds hurt our ears. And scare us out of our fur.
