My previous job - In orphanage

Before I came to JAXA Tsukuba Space Center, I was working in orphanage in my hometown, Nara.
I was taking care of children, washing their clothes, cooking for dinner, teaching their homework and so on.
The six children are my "sons", from junior high school to high school (all boys).
I lived with them under the same roof 24-7.
The children are lack of love from their parents from their early age.
Because of that they try to get attachment easily even from strangers.
At bottom, they have sense of doubt against adult.
Trainers have to  guide them in right direction, and help to stand on their own two feet.
Children must leave after they turn 18 years old.
After they graduate from high school, they go back home or they have to get work, rarely go to college.
They sometimes rebel against adult, but trainers need to teach carefully why they have to do something, how meaningful it is, and how to control their temper properly.
The most important thing is to "praise" children.
The more you praise children, the more often children do good things.
When children do bad things, sometimes you should warn them,  but in some situations you have to ignore them because by doing that they want to get attention from you.
It's very difficult task to take care of them.
In many orphanages, trainers and child minder are in overwork physically and mentally.
