Spell check...before spell check I was a much better speller. I notice the U in words like colour and sometimes that's what clues me in that a book I'm reading is not set in the U.S. The so-called extra U doesn't bother me. I feel we're losing something as things become more standardized across the globe but I guess we're gaining things too. In a way I cherish our differences when they don't mean that we want to do each other harm. I hope you can somehow manage to spell as you need to for work or whatever but still maintain a degree of English-ness in your English. It's part of who you are. I almost forgot, I guess there's really no such thing as French bread either.
I should never overestimate my basic arithmetic skills.
