Being the science student I am, my mind instantly went to the physics of why and what opaque is. The problem is that even I find that boring so I decided to come up with something different to talk about. The new problem is that I don’t know what to talk about now. Even when I image opaque I just see total darkness. Light being unable to pass. Nothing more than the literal meaning. I mean I could talk about ‘darkness’ in the more abstract sense, that probably could work in the sense but to me that doesn’t seem like opaque. I mean even though they technically mean the same thing they aren’t if that even makes sense.
