Do you think I am wrong to tell my best friend that I don't care if she's cold?
Why would you tell her such a cold thing?
I'd rather tell her the truth than be liked by her.
There may not be much to talk about between the two of you. As a result your friend may be looking to make something happen with telling you her status effects, like being cold, hoping for something to happen.
What's the matter with telling her the truth? Is it wrong to be honest?
You should not intentionally say something hurtful to your friend. Telling her you don't care about her being cold will make you seem apathetic.
