This is the case with most things in life. Wood is thermodynamically unfavorable, just look at all the energy released when you break it down (burn it). The reason it doesn't spontaneously combust is because the activation energy to start the process is too high. But once you kick start it the wood will keep burning until it is gone.
It's kind of like a glass sitting on the edge of a table, yes gravity would prefer it to be on the floor but it's not going to get there unless it gets some help.

Wonder if she falls for that...
Girls don't even like manmade diamonds even though they are more pure... The diamond industry has successfully brainwashed people to think that a diamond dug out of the ground with small impurities in it is actually better than a 100% pure artificial diamond. A jeweler can tell that a diamond is fake because it doesn't have crap in it when looked at under magnification...
Just do what I did and show your girlfriend the movie "blood diamond ". It's about how many of the worlds diamonds are dug up by slaves and have a bloody history before they become part of jewelry. My GF was all about fake diamonds after that. Lol.Edited by Epitope - 8/18/11 at 11:37am
