I think Charmion has nailed it: "The statement at issue is essentially an elision", and I don't agree with Reinhard's suggestion that the word "left" implies deliberate intention. "Left standing" does imply deliberate intention, but "left my glasses at home" could possibly be by deliberate intention or more likely could be simple forgetfulness, e.g. I left my glasses on the bus/at the pub/at the cinema etc etc.
