Sleeps Through Anything!

I've witnessed the girls both sleep through the house alarm and other loud noises but today's was a first. I was heading to my sister's and her family's new home when I realised my head was pounding. I decided to make a brief stop at mum and dad's for some cold medicine before continuing on. Mackenzie fell asleep in the car en route. I was pulling out of my parents' driveway, looked left, then right, saw the gold-colored van and then BAM! I hit someone's pretty mustang coming from the left. Though I'm still not sure where they came from. Their car did a 180 and ended up resting on the far side of my parents' property. I couldn't help wondering what CSI might show about travelling speed and what made the car do that. However, back to Mackenzie sleeping in the back. She slept through it all! She slept through my swearing, the bang of the impact, the screech of the tires, the police officer opening her door to peek at her, and my mother moving her inside for a sleep. We had to wake her two hours later when we were able to leave. Kinda of frightening to be able to sleep that soundly. Glad she's safe.
