I like to smile when its natural. I’m not mad or anything. That’s my style.

The speaker frames smiling as an authentic, voluntary expression rather than a constant performance for others. By stressing “when it’s natural,” he resists the expectation—common for public figures—that they must always appear cheerful or approachable. The follow-up, “I’m not mad or anything,” suggests awareness that a neutral facial expression can be misread as anger or attitude. “That’s my style” asserts personal boundaries and self-definition: he prefers to be genuine over perpetually “on,” implying that sincerity matters more than managing perceptions.
