Let's do the Time Warp again
"Who are you?"
"Ask me who I was." (Dickens 20)
I enjoyed this exchange, and found Marley's retort to Scrooge to be fitting. I can stand in front of a group and tell them about the person I am, and they may or may not find what I have to say worth their time. However, the chances of them caring increase if I can tell them a little about the person I was before this point in time.
Really, the destination means very little without mention of the journey.
Marley wasn't so lucky as to be able to show off his destination and journey. Instead of a congenial, "So, who are you, buddy?" from Scrooge, Marley got a stricken, doubtful, "Who are you??" And instead of being able to reassure Scrooge with, "OK, this looks bad, but think about where I was before," Marley had to say, "If you think this seems horrible, just consider what I did with my life pre-chains."
-A more pessimistic sidenote: At this point wasn't Scrooge's journey about over? I have to agree with Karyssa on this point, the guy seems pretty old. Maybe that's because of all the movie adaptations, but he's going to redeem himself of a lifetime of miserly actions with a few years penance? Ah, well, people get attached to their Christmas tales, so I'll let it ibe.
