But Nathan is unperturbed and quite unmindful of his ways. It is most vulnerable to the wandering footsteps of unmindful tourists. Unmindful of his injuries, Singh killed two more terrorists. Unmindful of the hazard attached to his mission, Cpl. Lange already knows of Pitou and is not unmindful of his charms. People walking past are unmindful of the chair's presence. Non incautus futuri is a motto meaning "Not Unmindful of the Future".
