When someone is talking about a famous person or a TV programme that I really ought to know about I often just say I was in prison when so and so was all the rage. For example, I really don't know what Ed Sheeran's music is like. He popped up in the news today so I thought I ought to give him the benefit of the doubt and well, what can I say? To me he seems like the personification of someone who thinks he is suffering from Imposter's Syndrome but has finally been rumbled.
