Brian, IMHO, you defend your daughter. I would ask your dad what that was about and let him know that it is unacceptable for him to treat his granddaughter that way. Your wife is a big girl and can defend herself, but your daughter is your responsibility.
You handled it well my friend.......With the wife.....
hey Brian, think you can DB your Dad and do this with no Emotion?? I think you should say something but say it in a non confrontational way and you should wait a day or two before talking to him.
My reasoning for waiting and doing it in a non confrontatinal manner?? This could be a trigger...you're worked up a bit. W is worked up a bit, D is worked up a bit..hell grandpa may be worked up too. Think about how you want to approach the talk before acting..
I still think you're doing good.
I hope you are taking care of "business". Steer away from any R talk at the moment.
