Sounds like that stryker got what it deserved! Sorry, had to say that. I won't stand for that to happen around my son and he is only 1. I have had episodes myself, but look back and think "Man that was a DA move". I would definitely consider a second chance since he is their grandfather, but only after a good long talk about it.

I had to put my foot down recently about the new carseat that my inlaws got to carry my son in. It was 13 years old, and faded and funky looking. I told them "He is not riding in that accident waiting to happen, I'll give you your five bucks back if it will make you happy". They understood, maybe not completely but they did.
