I hate to tell on myself. Like many, I started Kindergarten before SESAME STREET was a thing and my parents were not really helping me to learn how to read. (That changed later when Mom became a JW.) So I didn't know how to read until I was past Kindergarten.
So they started out teaching us the alphabet one letter each day. When day 17 started, I excitedly told another kid that I was thrilled to learn "elemeno" today.
I was in gifted class by 4th grade, so imagine if I could already read before Kindergarten like many kids today.
