DH speeding friend with DS

[Ariel896]

DH best friend took 8 year old DS out in his new car for a treat, driving 70 mph in a 50mph zone. I was really upset. DH said friend is a safe driver so wasn’t worried. I was clearly overreacting in his eyes. I’m really upset.

Why would they even tell you this information?

My DS told me

I'd be very angry at your DHs friend and tell them they're an irresponsible dangerous arsehole. Your DH is a twat too if he thinks this is ok. Don't ever let him take your son in his car again.
