I seldom use cash except when wheeling and dealing on a guitar. Pennies, nickels, dimes are a nuisance. The end up collecting in my car somehow. I play a game of trying to get rid of them when I go through a drive-thru restaurant. It the bill is $3.69, the 69 is made up of small change if possible.
I'm afraid small change will follow the Postal System to its demise. Times have changed. How long until we have no metal box on a pole at the end of the drive way? I've had two encounters with teenagers recently where it was clear they had no understanding of how to mail something via the USPS. This made me realize another aspect of the generational gap.
I have always LOVED sending and receiving mail. As a kid I was always writing letters to friends, etc and sending away for stuff. Now, I am one of the few to still write a letter every now and then. I still love it.
