Laughs Within The Tantrum

My wife called tonight. Rachel is in the midst of a wall-rattling, fierce tantrum. She doesn't want to take a nap. She's going to be hoarse tomorrow; that's how bad it is.
All of a sudden, Rebecca begins to laugh. A clap of thunder resounded over the house and the crying stopped abruptly. Instead, the baby monitor picked up a toddler voice saying, "Ooohhhh, that's not good!"
The tantrum soons resumes, however, as we hear a screamed, "I'm never gonna go to sleep again!"
