A teacher should not be an ice model whom students can admire but not imitate.
A teacher should set examples of a thorough conducting and personality, so he ought to be an upright person.
He should be close to his students, next to their issues and problems and joys. He should talk often with his students.
Now I remember a female teacher, a girl, who was so close to her students that some girls used to approach her classroom desk to just chatter with her and tell her about their daily stuff and problems, doubts, hesitations, perplexities, troubles… between classes. / Photo from: Cute-little-girl-in-rain-with-umbrella1 hdwallpapersrocks com.
