I actually had to explain to a therapist that even when people, like therapists, say there is no wrong answer, they almost never mean it. They might not want any specific answer, but they usually expect the answer to fall within a certain ballpark, and when you're on the spectrum, you can have an uncanny ability to answer outside of that ballpark, and it leaves the asker anywhere from baffled to frustrated, which in turns makes open questions frustrating for you, because you gotta figure out what they want first, and they won't tell you.
