I got chalk fingers right now and Oren said I'd break the teacup if I tried handling it. You're fortunate to have a master mixer make it for you!

[Iona isn't bad at making drinks herself; she's actually good. But she privately decided long ago that Oren was the best and his drinks always tasted better than anything she could make.]
