Little Star Nun: "Forcing smiles onto me is counterproductive."
Mother of Spice: "You are right. I will teach you artistry and fishing instead, that will make you happy."

Now that I'm looking at the boy on left, it doesn't look like it's the Blue jay monk after all, so I'm removing the tag.

On closer inspection of past posts, it appears to be the young monk on left of post #5536657 (the one with his tongue out). But I don't have a nickname for him.
