Kai at School

Kai is learning cursive alphabets in school. Yesterday they were taught to write the letter 'p'. The teacher then asked them to write 2 lines of 'ap', 2 lines of 'pa' and 3 lines of 'pat'. Everyone started working at it. Kai's partner made a mistake and wrote 3 lines of 'pa'. Poor little boy was about to rub the whole thing, which Kai saw. She told him, "I have an idea! you don't need to rub the whole thing but just add the letter 't' at the end and it will be done". A very simple thing which any of us would have done. The moment I heard this, I started thinking about how tricky a kid who is not even five can be??
