“For all his formidable self-confidence, he harboured doubts about the person he was at heart, and sometimes questioned whether he had a heart at all. Iris Caldwell, his girlfriend from Liverpool, recalled that her mother had accused him of being emotionally cold. It ate at him: years later, just before the release of 'Yesterday', Paul called Iris and said her mother should listen to Yesterday to see if it changed her mind. In an interview in the 1980s, he brought up the moment when he heard about his mother's death (‘What are we going to do for money?’), and said, ‘I’ve never forgiven myself for that. Really, deep down, I never have quite forgiven myself for that.’ As he danced through a Beatle life in which every door seemed to open the moment he touched it, he retained, in his mind, the baleful image of himself he drew as a teenager: a face that scowled rather than smiled. He once described his public self as 'pleasantly insincere’. He was drawn to those who saw through his masks and loved him nonetheless. Being accepted by John confirmed to him that he was special. Being loved by Linda, and by Heather, convinced him he was good.”
