Pardon me. I wasn't trying to say that other people's opinions should matter to the actor. Rather, I meant other people's opinions of whether or not a particular action is "fun" (and to what degree) for themselves would vary.

1. Billy might think sniffing glue is fun.

2. Tommy might not like it at all.

3. Suzie might enjoy sniffing glue, but not enough to give up her lunch money.

Now, as it happens, I would disagree with the proposition that other people's opinions should never matter at all. That wasn't what I was talking about, though.
