Letter Written in Hospital

We recently found this letter among my maternal grandmother's things. My father wrote the letter in 1980 during a stay in the hospital. The people mentioned in the letter are various relatives. It is strange to read a letter from almost 30 years ago that mentions people I know. It is also strange to see my 5 year old self mentioned in the correspondence between two people who are no longer alive. All of the people mentioned in the letter are either dead, or very, very different from the way they were in 1980. Lord have mercy ... where have the years gone? How did they pass so quickly?
