Speaking to a few students, I am humbled to understand the difficulties they and at times their family face. We as teachers often just see the student's face; never beyond... (in a way it is good). "Who they are? Where they come from? From what (kind of situation) they come?" we do not know... often we don't care to know.
When you ask someone, 'What do you get to see from top of the mountain?' of all probability, s/he would tell you about everything from the canopy to the flora and fauna EXCEPT the mountain on which they stand.
Teachers are in no way different. Very often from those high pedestal on which we stand, we see everything in and around the classroom except the human lives - so fragile - right in front of us.
