Explorations in SE Asia: Just what is is that I'm doing in Cambodia?

I suppose I should let ya'll know just what it is that I'm doing over here in Cambodia. The big picture is me travelling around South East Asia for a few months; adventuring, volunteering, learning, gazing in wonderment at all that is present in the world. Currently I'm in Siem Reap, Cambodia for three months. I'm here with a charity organization called Globalteers. They're help support many NGO's around town, with funds, volunteers, supplies, etc. The project I'm working with is called Grace HouseCommunity Centre. Grace House provides English classes for ~200 kids aged 5-18, vocational training (weaving and electrical wiring) and food for many of the kids and their families. I teach English lessons to kids who are 8-12 and of a level comparable to kindergarten-grade 2. It's grand. I have one class in the morning (2 hours), lunch break (2 hours) and a second class in the afternoon (2 hours). I teach the same material in both classes, more or less, so once I've done it in the morning the afternoon is just a repeat. The kids are great, they have such respect for their teachers, especially English teachers and they are so eager and willing to learn. I rarely have to tell them to quite down or pay attention or get them to stop mucking about. There's no way it kids at home would behave the same. There are 5 levels of class at Grace House, ranging from the very young (5-7) to the older kids (16-18). Each class has a Khmer teacher and at least one volunteer. In the older classes, the Khmer teacher teaches one of the hours but in my class I teach both of the hours. Many of the kids who come to Grace House where the same clothes every day and the only reason the brush their teeth is because we provide them with toothbrushes and toothpaste and they brush their teeth during the break.
