Here you see Matthew cutting the plastic, making sure it would fit the window properly.
In the meantime, Joey took a long piece of bamboo and cut it in four pieces lengthwise. Each of the long pieces was measured and cut to fit in the top, bottom, or either side of the window. Here is a picture of Joey looking like he's going to cut Matthew's hand off.
Finally, the plastic was wrapped around the bamboo pieces for security and then each piece was nailed to the window frame. I now have a hermetically sealed room. Aaaah!
What was most fun is listening to the guys while they worked. One of the teachers here said that the Vietnamese can do anything with almost nothing. He said it comes from being poor. I can attest that these guys can do anything they put their mind to.
