Sometimes it is really hard to make a person believe something when they think another thing might really be the truth. Like how Mimi was thinking that maybe I wanted to be best friends with the Graces instead of her, which was 100 percent not the truth. And if this kind of thing happened, then you could be wishing that you had a real magic bead-head necklace to make a wish on so the not-the-truth feeling would go away.
But I didn't need that because I had something better, and as soon as I showed it to Mimi she knew that we were still the best friends ever. And when we hugged she didn't even have one sneeze!
