Definition: When someone operates on hyper-alert environmental scanning mode, constantly sweeping their surroundings like radar for micro-opportunities to assist others—even if it means sprinting to lend a stranger a stadium towel or refolding a laundry pile no one else cares about.
This isn’t performative kindness; it’s an involuntary reflex wired by empathy. Radiar users preempt needs before you voice them, turning minor inconveniences into moments of grace—like Venmo-ing you mid-bite or pushing in chairs like it’s a sacred ritual. Their “harmless” habit screams: I see you, and I’ve got your back.
