Psy also follows the rules(Most of the time). So Psy Follows the rules, people are comfortable with him, he is trustworthy, respectable, and I love him. Sounds like a perfect mod to me.

But then there is Del, a much more serious person(but still with a sense of humor). He also follows the rules, and he is also trusworthy, comforting, respectable, and lovable.

Being constantly funny and jokey are fun, but thats not all people skills are. People need to be helpful, and strong, and nice as well.
