I'd be glad to teach my native language, whatever I consider myself excellent as well. I like to share what I know

I love sharing my knowledge to others and at the same time as I teach, I learn. Whatever you need to know, just tell me and we can figure it out together, what a better way to learn than sharing and arguing about what you study? It is said that you need to know how to explain a subject in order to know you understand it well.
