I was writing a response to a forum post in Russian and thought to run it through Google Translate for verification. If nothing else, it would catch the sort of misspelling I tend to make.
It surprised me by completely reversing the meaning of what I wrote:
This is the first time I’ve been irritated enough to correct a Google translation. It’s a common word, so I’ m not sure what could have led to the misapprehension on Google’s part.
