R.J.
I CAN activate the filter between my brain and mouth on occasion. I usually choose not to. So I comment on the world around me all the time.
Anything beautiful: voices to clothes... I tell people
I have this odd Nikon shaped appendage. I take photos of people, really gorgeous candid ones (I'm NOT a photographer, I just like shooting)... Edit them, and give them away. We're talking most strangers. When I happen to catch a great shot, I just ask them for their email and show them. I'm still irked that the little girl at the beach seemed to be there with no adults at ALL. It's one of my altimeter favorites... And I can't get it to where it needs to go.
When someone is buying $2 worth of gas, I used to always give them a $5 (money's too tight right now, but I did it again last week... It's just reeeeally rare). Regardless of their appearance. Wealthy people do boneheaded things, too! (like forget their wallet at home).
I thank EVERYONE with whom I interact with & try to get to know all the regular guest stars in my life (my mail carrier and all 7 employees at the gas station, and about half of the grocery store are actual friends, now... Like home numbers. And I know my garbage & recycling workers names & general info, etc.). Very few people LIKE feeling invisible. Most people have something special or interesting about them.
I nod to people walking by me / make eye contact.
I introduce people I think might like each other or be useful towards one another.
I ask old men for directions rather than look at a map (old men are the BEST source of local info, btw, and they're totally marginalized! Old men are terrible flirts, and in general very much wanting in being needed. These men fought our wars, built out cities, raised our parents... And they're just left to rot, more often than not. It's amazing how different my life has been for the conversations on the side of roads, cafes, etc.. 'Excuse me, sir?' is better than google.
I dunno. Just sorts normal, everyday, being nice... Right?
