Kids are funny little people

Today at the dinner table the kids were arguing over what a rectangular prism was and weather or not that is the shape of a gas tank. Little A was drawing it in the air and Little D was correcting her. She had it just about right

Also and interesting conversation about staring contests.

Then there was talk about Justin Bieber, wherein Little A says, "I can't say his name cause it freaks me out!"

There was also talk of who Little D was going to marry, which I must say is a much better choice than his last one. This one is at least a member. He said that they already had a "conversation" about it. I didn't realize he knew the meaning of the word conversation.

Where did these kids come from?
