Thank goodness it was just the car. I remember the look on my Mum's face when she and Dad came to get me after being involved in an 8-car pileup on a VERY busy motorway at rush hour. I'd left the house not half an hour before on my way to school (17, had my licence 3 months) and she gets a phonecall - "Mrs Bee"......*silence*....."Hold the line"....."Mum? I've been in an accident, I think the car's a writeoff". Mum's response was something along the lines of "F*** the car, are you okay????". Wasn't my fault, nothing I could have done to avoid the idiot who ran up my butt and pushed me into the car in front who then dominoed it forward, all at 100km/hr.
The car was a writeoff which we couldn't afford, but the insurers latched onto the fact that the guy who'd hit me had not only left the scene of the accident he'd caused, he'd not even bothered to check that anyone else was okay. I was standing on the side of the motorway in my school sports uniform, panicking because I was going to be late for marching band.
Never mind the whiplash injuries, I needed to be at band warming up my sousaphone!
He'll be okay, and while the lecture will happen, both your husband and son will lie in bed afterward thinking, "It could have been worse".
