Those are probably some of the clearest indicators, even if you aren't actively trying to visualize the person. I think to take it to the level you have, you've gotta really notice different folks week after week, something I don't really have the time/energy to do. What you're saying tho, makes a great deal of sense. Yeah, what about my sig, I should probably jus walk around with a sign around my neck! Oh well, they're good for a laugh
