I read this at PostSecret. It's quite scary when you realise that the person behind the voice might be that very quiet student of yours. Simply because the fella is well behave and presents no behavioural problem whatsoever even when taunted by friends, does not mean the fella is coping well. Although it actually might, but it can also mean thatt the fella is afraid to speak up. In my line of work, I have to constantly remind myself to KNOW my pupils.
