<---closest I could come to a Bobby icon for the time being :P

Yeah, I'm not saying Bobby would be great as a parent either. He'd just be different than John, and that's what matters to Bobby. But it's exactly as you describe - whether you have personal experience with having kids or not, there are circumstances when you feel you can criticize someone's parenting skills.

I think given the level of affection Bobby as for Dean - it's pretty easy for him to find fault with John for how damaged Dean is...whether or not that is completely justified is besides the point.

I've been reading metas all day :P
