person A: I was in a work meeting the other day and one of my coworkers was was able to recite from memory a whole lot of legal policy and verbiage. I was floored by how much he had retained from studying! 
person B: Oh wow yeah that is quite impressive! He should become a lawyer if he isn't one already!
person A: I was thinking that he must have some kind of photographic memory!  I could never have remembered all that stuff!
person B: Yeah_comma_ I have heard some people have that! Sometimes after just reading a bunch of information just once can remember every single word!
