What characterizes a "furtive" behavior?

Furtive behavior is characterized by a sense of secrecy and caution, often arising from a desire to avoid detection or draw attention to oneself. This type of behavior typically involves subtlety and a certain degree of wariness, which aligns with being marked by quiet and caution. Such actions are often performed in a way that is discreet or stealthy, possibly due to feelings of guilt, anxiety, or the need to hide one's intentions.

In contrast, behavior that is open and honest lacks the secretive quality associated with being furtive, while bold and brave actions are tend to be conspicuous and assertive, directly opposing the idea of stealth. Energetic and loud behavior also does not fit the definition, as it is public and attention-seeking, thereby contradicting the cautious and subdued nature of furtive actions. Hence, the description of being marked by quiet and caution truly encapsulates the essence of furtive behavior.
