(scene opens in messy kitchen)
Beta: Hey! What happened to all the cookies!?
Me: You mean the birthday cookies you made for me yesterday?
Beta: Yeah! There are only three left!
Me: You mean there are only three of MY birthday cookies?
Beta: (failing to pick up on warning tone of voice) You weren’t supposed to eat them all, you were supposed to share and give us more than one of them!
Me: (simmering) Go do your homework.
