"Off his guard" is an idiomatic expression used to describe a person who is caught unprepared or without their usual vigilance or awareness. When an individual is off their guard, they are not as attentive, cautious, or ready for potential threats or challenges as they normally would be.
Being off one's guard often occurs when someone feels relaxed, comfortable, or complacent, leading them to let down their defenses, both mentally and physically. This state of vulnerability can leave them susceptible to unexpected events or actions that may take them by surprise or disadvantage them. It can also make them more prone to making errors, overlooking details, or being easily deceived.
For instance, if a person is engrossed in a conversation or deep in thought, they may be off their guard and fail to notice their surroundings or potential hazards. Similarly, when someone is physically tired or emotionally preoccupied, they may be off their guard and overlook important cues or signals.
Being off one's guard is not restricted to physical contexts and can also refer to mental and emotional states. It can imply a lack of attention or alertness that can be exploited by others, whether intentionally or unintentionally.
Overall, the term "off his guard" emphasizes a temporary lapse in preparedness, awareness, or caution, leaving an individual vulnerable to unexpected circumstances or actions.
