Wow.
To be impressed is one thing. Shocked and awed by the skill and talent of something that you stand up, clap,your mouth forming the word, "wow". A standing ovation to a brilliant talent soon forgotten as the night goes on. To be IMPRESSED is another thing. Not even having the sense of mind to react, paralyzed by something so weird yet outstandingly beautiful. Mouth open, eyes gaping, breath hitched, no words coming out of your frozen mouth. As if no words would actually compensate for the shock and joy you've experienced. Not wanting to believe what you saw or heard, but thanking God that you did. That's not being impressed, it's disbelief. Disbelief that something you didn't know could be done or could exist, was right there, beaming.
