Typically, a Sagittarius man is not a "sneak" in the traditional, underhanded sense. His planetary ruler, Jupiter, encourages expansion, wisdom, and a broad, ethical perspective. He is more likely to be brutally honest, even if it causes temporary conflict, than to be deceitful.

However, his desire for freedom and avoidance of drama can sometimes be misinterpreted. He might:

• Withhold minor details if he thinks they will lead to an argument that cramps his freedom.
• Change plans suddenly based on a new opportunity, which can seem evasive.
• Seem distant when he's mentally exploring new horizons, not because he's hiding something.

This is less about malicious sneakiness and more about his innate need for independence and aversion to feeling trapped by expectations or emotional scenes.
