My favourite old colleague at the bank went with "do you like marvel" as an opening salvo, then when I said no, proceeded to show me photos of his "man cave" packed with action figures and posters and shit anyway, I admired his refusal to change his predetermined conversation. He was obsessed with cricket, football and NFL though so maybe I'd look back on that moment less fondly if he'd continued to talk at me about iron man for the next four years.
