October 5 is the professional holiday for teachers. On this day all students congratulate their teachers, give them flowers and cards, and express their gratitude towards their favorite teachers. Flowers, flowers, flowers, lots of flowers in every school… everywhere.
Normally teachers get together after their work hours and have fun.
It’s customary to congratulate your former teachers too. It’s very touching when you see a grey headed person with a bouquet of autumn flowers who comes to see his old teacher and says ‘Happy Teacher’s Day”.
