Hostility grew between Jones, Jagger, and Richards, alienating Jones further from the group. Although many noted that Jones could be friendly and outgoing, Wyman, Richards, and Watts have commented that he could also be cruel and difficult. By most accounts, Jones's attitude changed frequently; he was one minute caring and generous, the next making an effort to anger everyone. As Wyman observed in "Stone Alone": "There were at least two sides to Brian's personality. One Brian was introverted, shy, sensitive, deep-thinking. The other was a preening peacock, gregarious, artistic, desperately needing assurance from his peers." Wyman added: "He pushed every friendship to the limit and way beyond".
