Using something like email to keep everyone up to date and sharing a good joke with everyone would have been a lot of fun for him. This was one way he helped the siblings stay in touch and know what was going on because they were scattered about in several states. Many times he would include letters he had received from some of the other kids. He also loved to share jokes and would clip something funny out of the newspaper to send along with the letter. He had 6 kids and would write letters to them on a regular basis. I have always said that my grandpa would have loved email.
When you think about the number of other people who do the same thing, that is a huge chunk of money the postal service is losing out on every year. I pay almost all of my bills online anymore and rarely send one in the mail. The cost of a postage stamp keeps going up as well. Our delivery service is also quite slow and some days we don't receive our snail mail until 7:00 pm. Some of the smaller post offices across our state have closed down. I can't help but think that email and technology have played a big part in that.
The US Postal Service has sure gone through a lot of changes in the last several years.
