Here we are!!!

-I'm six years old. It's time to go to school!!! I'll learn a lot of things,...everything!!!
I'll meet new friends and....a teacher.!!!oh!!! a teacher...???
A man or a woman? A young one or an old one? a smiling or a stern one?

There are a lot of teachers in Greece - like in all countries - but we'll see a common one.
