grand central conflagration: seriously, what is it about lines?

(this is not grand central. but it is certainly majestic.) ruggy and i were in grand central station, on our way to a lovely evening. of course we were running late.  i made ruggy promise to slow down, as it was totally our friend's fault that we were late, and friend could pick us up on the next train or i could break my ankle running on the decrepit subway stairs. this always gets ruggy.
