it's "labour"
Perhaps...but why add another letter when it's really superfluous? However, maybe we should start a discussion on the correct pronounciation of words (e.g., aluminum)? That'd be a read s.storm... 😂
For some reason I regularly try to spell words with British spellings even though I am American. Normally I catch it and fix it, but my first thought is the British spelling. I have no idea why.
