Way back when, a friend of mine was ridiculously obsessed over the current 'teen heart-throbs' of the time. Her family went to Europe. I don't recall if she toured the house itself or just an exhibit on it, but it affected her.
When she told me about it, she said, 'I know we read the book in school, but it never really clicked that she was an actual person. And I was standing in that place looking around her room and thinking how much she and I might have had in common. She was just a kid, the biggest worry of her life should have been whether or not was going to be the 9th caller and get the NKOTB backstage passes not 'if I sneeze right now is someone going to hear and get my family killed'"?
I am going to assume, charitably, that Mr. Beiber's train of thought was going on a similar line and just derailed at 'poorly expressed' station.
