How inspiring! My guess -- but this is only a guess -- is that this little koan was meant to be part of a bid to encourage me, the mortgagee, to enroll in an electronic payment plan. This would "make a difference" by saving the Wells Fargo Mortgage Company the expense of sending me bills and by eroding my day-to-day control over my household finances. Oh, by and making an unmeasurably trivial reduction in my personal share of the planet's paper use.
But whatever its original intention, somehow it has been divorced from its referant and now just sits there on the envelope, mildly encouraging us to shake our fists -- or at least wag our fingers -- at fate.
Gentle Reader! I encourage you to do one thing different and make a difference! And report back in the comments.
