Body language, reading lips, and somesuch, sir.
Actually in real life, it's pretty pathetic. I was there for three hours, and a lot was said, but those few points were the only things I could grasp.
I'm always kicking myself for the 90% that I do miss.
OK, just curious. I’m hearing impaired in that when there is background noise (like loud music), it is almost impossible for me to keep involved in a conversation. So I can relate in part to the frustration of missing most of what is being said around me.
