Lol, have not thought of that waving part. And when I decide to walk as part of an adventure, I am not sure I would walk somewhere in particular... I might just walk and see where my curiosity takes me. Made me stumble over the home of a previous president in a certain tropical paradise I have been in .You got some great advice here from fellow RFers!
Try this. Go outside for a walk, and smile and wave at the neighbors. I've found that simple actions like this are enough momentary reminders that people are awesome since 99% of the time, they smile and wave back at me.
You get some fresh air, a little bit of sunshine, it's free and doesn't cost any money, and if you're feeling a little adventurous you'll walk toward a destination that captures your interest where new people await your presence.
