Yes I spell in a way depending on what kind of mood I'm in on that day, and it is true that there is a slight difference in spelling between the USA and Australia, but there is also a different way of spelling in Sydney Australia as well. If you come from The north side of sydney you spell like the english, if you come from the western suburb of Sydney Called Bankstown, you would need to have some one like me to translate and spell there form of english to a Thai persion, Eg Brother is spelt Broe, friend is spelt "dood" words like cobber, trueblue, groover, are the form of english that I here as I work in this area, but I live in the east so I spell differently again.
