A neutral character does what seems to be a good idea. She doesn’t feel strongly one way or the other when it comes to good vs. evil or law vs. chaos. Most neutrality is a lack of conviction or bias rather than a commitment to neutrality. Such a character thinks of good as better than evil. After all, she would rather have good neighbors and rulers than evil ones. Still, she’s not personally committed to upholding good in any abstract or universal way. Neutral is the best alignment you can be because it means you act naturally, without prejudice or compulsion.
