When you think about it, who is going to point out a boob increase? Other than the Elders wife. She will point out that Sister A now has bigger boobs. What is Elder Joe supposed to do? Say "Yes dear, her breasts do look better. Nice size, shape, perky. Huh, I'm glad you pointed that out. I think I'll go tell Elder Tom and Elder John so we can have a JC. She can tell us when they were done. We may have to have her show us the scars to have proof. Since we'll all be there, we'll have our three witnesses to the offense. I'm wondering if they went in under or through the nipple. Just don't tell Sister D, she is such a gossip."
His wife would kick his ass for pointing out how nice Sister A's boobs look.
So, the better thing to do is look and shut up. Surreptitiously of course. When you're holding the microphone over her head.
