Paying bills A post box full of bills and only one postcard virtual cards do not count; it is like virtual flowers you see them on a screen and smells of laziness and a forced duty to send something to show appreciation. Bills are more trustworthy they want payment now and follow up if you haven't paid in time with a stern letter typed words on paper and you can't pretend having forgotten it. I have the bills in front of me, but will not pay before I get the stern letter, showing me they care.
