What would you guys say are types more prone to being formal/serious? Does not preclude being an extrovert or a feeler. I crack jokes regularly but I'm still by nature pretty serious looking/seeming; I just come off that way. People say I take myself too seriously. Lately I have been realizing with some other serious people, I can't completely relax because we are both so formal in general. Does this kind of trait have smthing to do w typing?
