 It is natural for someone to feel fear when they think that they will not be able to make it to an important event, such as a birthday party, so someone saying that they are not afraid at all is being sarcastic.
Context: I am worried I will not be able to go to my fathers birthday party.
Hypothesis: I am not afraid at all that I will not be able to make it to my fathers birthday party.

Given this context, determine if the hypothesis is true (Yes, no, or unknown)?
