It is normal to feel jealous when someone gets something that we want, so someone pretending to be happy for the other person and not feeling any jealousy is not believable.
Context: "Becky got new shoes and they were the ones I wanted." Claim: "The fact that Becky got the same damn shoes that I wanted so badly makes me really happy for her."
Considering the context, is the claim true, false, or unknown?
