Well finding out the size of their credit card debt might not be very nice. Or bringing them to your belly button lint collection. Or a long condesending math explination over just how many half sheets you need to save in order to pay the electric bill from even using the dryer. Oh wait how about a rant about how this decadent western civilization is ruining the environment! You are just doing your part.
Truthfully as one who used to roll eyes (albiet behind peoples backs) I have to say a look of sympathy is prolly the best return. The poor dears have no idea what they are doing.
Oh and BTW do you cut them one at a time as you use them or is there and easy methd of cutting the whole box?
