Most people would feel disappointed and angry if all the classes they wanted were already full, but in this person's case, they feel like throwing a party which is completely unrealistic.
Context: I can't believe all of the classes I wanted to take are already full!
Hypothesis: The fact that all of the classes I wanted to are already full makes me feel like throwing a party.

Given this context, is the hypothesis true (Yes/No/I don't know)?
