From Texas, in general we usually smile back or nod our heads. Some form of acknowledgment, but my pissed of meter by mid day is normally at 80-94% so I may just nod my head without a smile. But it’s nothing personal.
Depends on who they are. If I get their vibe and stuff, for sure I’ll smile back, but if they’re looking kinda sus, then no
No because you never know where they been
I think it depends on who smiled at you. I’ll probably smile back if you’re a friendly neighbor. But if you are a completely strange boy, I will probably make a strange smile trying to show that I am not as comfortable or confident greeting you, at least to make it clear that it was weird that you greeted me
a guy on the bus gave me the creepiest smile once so no bro, i aint risking it
