Once a #teacher, always a teacher! | 1 Mar '16 | iPhone 6s | #aroundtehran
Today is the Teachers' Day in Iran. While other occasions like the Farther's Day, the Mother's Day, the Valentine's Day, etc. are widely celebrated, the #Teachers' Day in Iran is relatively less noticed and is celebrated only among teachers themselves and at schools only.
Happy #TeachersDay to all teachers!
