On my way home, I waved at fennel in his office, as I do several times a week. This one-second interaction is disproportionately cheering about 99% of the time, considering its size and scope.
Then I passed my downstairs neighbors as they headed into Davis; we smiled at each other and said hi, but didn't stop. And as I was crossing Willow Ave, I heard a voice calling my name and turned to see my friend Katherine driving by and waving at me. I hardly ever see her, but it made me smile just to pass each other and wave.
And all of this made me think about how much I value these little interactions and how they all disproportionately brighten my day and sense of happiness and well-being. I like that my life is such that I can live in a big (to me -- remember, I grew up in a town of 200 people) metropolitan area and still have many of the pleasures of small town living.
