It's not what you would expect maybe, but it's something I'm proud of. While I was in Ho Chi Minh City (Saigon) I volunteered for two weeks. Initially it was to be at an orphanage/Buddhist temple where they have very little money and subsist primarily on donations. I thought I would take a bunch of toothbrushes for the kids to use. Instead it turned out that we worked at a state school for the children of the very poor. As it was explained to me, these were the kids who would otherwise not have access to any education at all. It was our task to help construct a shelter for motorbikes and to teach some English, real basic stuff. I worked with the volunteer coordinator, "Mr." Thanh to come up with a fun page of food items that the kids could color and learn.
At the end of the two week program, the Finnish volunteer Lauri and I got the other volunteers (about 19 total) to kick in some money for a whole slew of toothbrushes and toothpaste and we gave them out to the kids and did a little presentation with this cartoon I did with the help of Trang, one of the other Vietnamese volunteers.
I like drawing big teeth, so it worked out well.
