We were at easy child's 4-H dog show today, and difficult child was playing with another boy. Apparently they bet each other that they could drink a whole bottle of water without taking a breath. difficult child told other boy to breathe thru his "male organ" (to avoid censorship) so he could drink the whole bottle. I realize that difficult child was way out of line, and I do not know if other boy's mom heard. The boy came up to me and said do you know what C said, and then told me. I told difficult child and boy that they should not play together anymore, and difficult child was either with myself or husband the rest of the time. The boy difficult child was playing with was several years older than difficult child. How horrible is this???
