At a party, it is not desirable to feel alone and so someone who is happy that their friend has ditched them to go talk to someone is being sarcastic.
Context: "My friend left me all alone at this party to go hang out with some guy I've never met before." Claim: "Feeling so awesome at this party because my friend ditched me to go talk to some guy she just met."
Considering the context, is the claim true, false, or unknown?
