Richie was messing around with those sus chords and Jon had the melody and parts of the lyrics already (with also I'm guessing the title). It was a true collaboration from there, and this was also said by Richie around the These Days release in that guitar demo they made of him. He's just at a stage in his life where he feels the need to inflate his ego, it'll pass I'm sure, everyone has insecurities, and he's been in Jon's shadow for a LOT of years.....
