When people say "Unbelievable" in texting, does it usually mean "Unbelievably good" or "Unbelievably bad", or neutral, when the context is unclear?
Details about the background:
I send something neutral and playful to a friend, and the friend replied "unbelievable" without any additional words or follow-ups.
When the details are missing, how would you usually interpret the mood or attitude behind the word "unbelievable"? Positive or negative?
