You're correct.

If you're a good friend, Optimistic, you'll sit, talk, and comfort your friend. You may want to try and make her see things your way, but don't try and impose your opinion on her. The best thing you can really do for her is be there when she needs you. Either she'll come around on her own, or she won't. Not much you can do to change that, probably. If you push too hard, you may just exacerbate the situation.

But that's just my opinion.
