My husband is not used to using pencils and paper; perhaps most developers are this way. Most writing is illegible and occasionally, there are symbols or binary. In our love notes from high school, he would jot down code and it bewildered me. Now he writes hearts in all of the cards he gives me. They are written as if he typed them with a keyboard and had to resort to <3. He’s like a computer or a little WallE. At least I understand what the hearts mean!
