Letter from Little Bro 1989

One of my favorite things about keeping a journal, especially before the digital age, is finding hand-written letters I saved! I was thumbing through a journal from 1989 and found this treasure from my little brother who was 7 years old. I was away at college and loved writing home. This was his reply. I am actually impressed for him being such a little guy! Do 7 year old children talk about having babies together?
