Everyone always said that Ringo was the nicest and easiest person to be around. Wonderful sense of humor and lots of fun.
Tom Petty said that he thinks John formed George's personality, therefore George could be "grumpy" as Jeff Lynne says.
However on spiritual matters, George is the man to talk to.
John would much rather watch TV ALONE than party with anyone.
Too insecure, he just wanted to converse with his gophers.
A captive audience.
Paul is always said to be the hardest to get to know, so superficial small talk is certainly possible.
