My son is a senior in high school, and we were all a bit surprised when a letter showed up in the mail the other day addressed to him in a childish scrawl - especially as it looked like his old handwriting. It turns out that his sixth grade teacher had all of the kids write themselves a letter back then and had held them until now for mailing. It was a great idea, giving the kids a look at how they predicted they would be doing in high school.
Visitors to Expo 85 in Tskuba, Japan could do the same thing. Letters placed in this special mailbox were to be held until 2001 for mailing. I wonder how many letters actually got to where they were supposed to go, given that people often move within a sixteen year stretch. I also wonder how they dealt with the rise in postage rates. If anyone has seen one of these letters surface after the fair please let me know.
