I had thought this really wasn't a Big Deal. But then I casually mentioned it earlier today when an ex-colleague and her daughter popped into work. Both of their jaws dropped open in shock. Then my supervisor came back in the room and they turned to her and told her too. Slack jawed shock was also her reaction.
So I guess it's a bigger deal than I thought and maybe I should just 'fess up.
I've never seen an episode of Doctor Who. Ever.
