Hmmm, I thought that if you sign an agreement... it does not matter whether you "mean it" or not. You signed it, so it has to have some meaning.
Or, can you back out of a signed agreement by saying "Oh, I did not mean it"?
Not an expert, but seems dubious/shady.
Your honour you see I signed it so I could trick them! It was super sneaky - anyway so since I signed it left handed I don't have to honour it right?
