David's only just explained that he had an average teenagerhood, full of unhappy but also fine moments, and she said she felt worried for him suffering through a torturous misery. What the fuck, Anderson? He chose Walking on Sunshine as his first track because, and I quote, "it's a happy song". At which point she, for some unknown reason, then said she imagined him dancing to 'Walking on Sunshine' at a school disco (probably alone with a hopeful look at nearby girls and plastic cup of fruit punch that he would later spill down his Sunday best. She didn't say this bit, but I am almost positive that was her vision.) Oh, and now she's asking him why he didn't like puberty. Why would anyone like puberty?
Put the proffered razor away, Anderson! Now you've got the poor sod choosing Radiohead! He's already on your projected downward spiral! Your work is done! (Actually? His reasoning is hilarious and applause-worthy, and he seems really very cheerful about it. But the point still stands!)
