Olivia is drawing on her doodle board before bedtime, pretending she is a teacher. She wrote a "q" and an "a" on the board.
Olivia: What is the difference between these?
Me: One is a "q", one is an "a".
Then she erased it and wrote the same thing again.
Olivia: Now, look at them again, what is the difference?
Me: (Then I wonder, maybe they are not alphabets, so I said:) They are both circle with a line. One line is longer, the other one is shorter?
Olivia: No, (she pointed at the "q") this is the "a" you learn in PK1 (preschool 1), (while pointing at the "a", she said:) this is the "a" you learn in Grade 1.
