Why do you need to add "meg" at the end?
'endre' cannot be used intransitively, it needs an object.
makes sense, "I cannot change... (Change what?)" definately sounds like an incomplete sentence to me as an english speaker. But english speakers say it all the time so (myself) is implied i guess
...even if I could. Even if I wanted too.
Is it possible to use the passive form here? "Jeg kan ikke endres"
