Oh, thats weird. I was talking with my friend about this last night. He said it always interesting to see what alignment you think you are and then compare that against what others would pick for you. But in my case we both said Nuetral Good.
Seriously though.. i kind of understand it but don't understand the full meaning of each option, i assume chaotic good is something along the lines of always do good blah blah.. whatever the option for "grey" is, that's me.
