My wife's father is an old school bad guy.  He was abusive to my wife's mother, abusive to his daughters, abusive to his other wives.  So at the time I proposed to my wife he wasn't around to ask for permission.  Regardless, had he been around at that time in the role of "bad guy" that he perfected then I doubt I would've asked.  A true father or mother deserves to be asked, but a man like that.....no, they don't.   Today, he's older and regretful and he's workin slowly to build the relationships he destroyed.
