This is when bad things happen. The mom is just trying to be a good mom, but she's also trying to go back to sleep. So, she doesn't turn on any lights. To turn on lights risks the waking of the entire house. To leave the lights off risks the chance of kicking the kitchen chair that didn't get tucked in just right.
This is when the mom again proves she is crazy. Because even though she almost passes out from the pain, the pain is soon triumphed by her anger. Anger because this mom has a million things to do this morning and urgent care wasn't supposed to be on the list.
