Losing Your Marbles

I could hear Holy Terror arguing with Billy in the frontroom...it was getting heated. Finally, he comes stomping into our room where we're still laying.

"Billy won't let me play with those little balls!" he cried.

"They're marbles, honey, and are Billy's," I replied.

"But I want to play with them!"

"His marbles are very important to him and he doesn't want them lost," I said.

...Really, does anyone want to lose their marbles?!
