Navigating Trail Etiquette and First Impressions

I spend a lot of time on the road for work, so hitting the trails is my escape. Lately, I’ve been meeting more people out there, and I’m curious about the unspoken rules. What kind of small gestures or conversation starters make those brief encounters pleasant? I don’t want to intrude on anyone’s solitude, but a friendly nod or a quick chat about the conditions can be nice. How do you strike that balance between being approachable and respecting personal space?
