Yes, I’m in pursuit of it. Happiness. I’m on the lookout for notable examples of the phenomenon, to see if I can make any sense of where it happens and where it doesn’t. I might record them in a book, too, as something to turn to on rough days, to lift the spirits a bit by the recollection of being caught up in the infectiousness of an unaffectedly happy person. Hey, it’s no sillier than collecting spoons or snow domes, is it? Little reminders.
