Do you have spell check on your browser? You may have turned on a different language and now you are having your spelling errors highlighted?
Maybe it's set to Norwegian. Jeg heter Amy og jeg kommer fra..... ok yes it's set in Norwegian because apparently that was all perfectly spelled English lol.
You don't wanna learn Norwegian. It lacks words and is far too reliant on context sometimes. Back on the subject of blogs...I've just found out that someone used wax because of my blog, despite the fact that I went through all the old posts which mentioned wax (thoroughly I thought, but I must have missed something), redirecting to an anti-wax post. This is annoying. Grr.
