Another classic personality trait that makes a good Trait:

You are generally happy. Most of the time, you enjoy yourself. You usually seem to have a smile on your face, and your expression matches your feelings.

Other people might take you less seriously, or believe you to be a fool. (People who are Sardonic or Serious, especially, might be prone to this.) You might respond inappropriately to distressing news or serious counsel.

But your bubbly demeanor can help forge deeper bonds of friendship, and help buoy yourself and others in times of crisis. It may make you hard to perturb, or to sadden.
