6 year old: "Mom, is that a baby wipe that Fr. Verrier is using to clean the ciborium?"
(okay if she has the vocabulary to know it's called a ciborium doesn't she have the vocabulary for the purificator?)
Me: "No, it's called a purificator. But you are right that it's used the same way. He's cleaning everything up after Mass."
And then I see the smirk on her face.
