To Those Without Kids...
Your children will be acutely aware of when you need to be up early and well rested, and do everything in their power to prevent you from getting a full night’s fitful sleep including asking you questions about the simplest almost rhetorical things that you’ve never had to answer and screaming so loud that they strain their larynx so that they have to scream even more.
They will do this until you just decide that you’re ready to feed them whiskey or toss them to the curb just to get 10 minutes rest, and then they’ll suddenly outright stop, leaving you mangey from pulling out hair, and irrevocably insane.
