Learning and teaching chemistry

In the past, when I was learning chemistry as a student,
I constantly bugged my mother, who is a chemistry teacher, about the many misconceptions that I was blur about chemistry.

In the present, when I am teaching chemistry as a teacher,

I still constantly bug my mother about the many misconceptions that I am still blur about chemistry.

And I bug her about one more thing now,

how to convey chemistry concepts to students.

I think she wonders what I have learnt in 4 years of studying chemistry in university.

Sometimes, I wonder too.
