I have a vague idea of the schedules of the "consequential strangers" in my life; the people that are just sort of there and maybe not noticed much until they are not there. I tend to do what I need done when they are working. I didn't start off doing this as a planned thing; it happened over time. When I finally noticed what I was doing, I tried to figure out the "why" of it.
Simply enough, they seemed happy. They were doing their job with a smile. They were invested in me while I was with them. They were helping to make today a good day. I find myself responding in kind. Then I find that it carries over to the next person I encounter. I'm making someone's day better.
As we go about our day it makes sense to notice the interactions we're having with our family, our neighbors, our friends, our co-workers and all the other people in our neighborhood. We should take a little effort and try to make their lives better by being invested in them. By making their day a better day, ours is more likely to be a good day.
