I knew that some envelopes are undeliverable, but didn't know that they had a whole plant dedicated to decoding bad handwriting!
The other thing that I was known for in our family, was reading letters that other people couldn't make out. My Aunt Nora - great aunt, actually - had difficulty writing, but she sent letters anyway, which I loved getting. However, no one could make them out, so I did, and would read them over the phone to my mom, etc.
It's kind of scary that young people don't know how to address an envelope or write a check. There needs to be a small amount of time devoted to those things and others (reading a regular clock, etc.) both in grade school, and maybe a class in junior high - even if only one semester.)
We had a practical math class in junior high once. It taught us about tax forms, and such. Heck, you can (some places won't fund them anymore, I know.) take a semester of sewing, cooking, or shop, so why not reading an 'old fashioned' clock, filling out an envelope, or check?
I'm not even going to start on handwriting.
