Seeing someone smoking can be concerning because it is a major health hazard and can lead to cancer, so someone who feels happy about it is not being rational.
Context: "I hate watching my parents smoke, it makes me really sad to think they could face cancer as a concequence " Claim: "I feel so happy every time I see my parents smoking because I know that cancer is a very real possibility for them"
Considering the context, is the claim true, false, or unknown?
