You're worrying about what other people are going to think. How do you think you handled the situation? What would you do differently, if anything.
If you're raising them, they answer to you. Too tough if Dad is going to be there. Remind him that things would have gone smoothly if your son hadn't come home with an attitude and bad mouth. And yes, he'll get defensiv.e What's his role in their care and wellbeing?
Sometimes, the hardest lessons learned are those where we are kicked the hardest in the butt. If he came home with the attitude, it's easy to see where he got it.
It takes time, but taking control of the kids is really important with the alcoholic parent. They see mom or dad acting a certain way and realize that if they do the same thing, they'll get what they want. Their inheritance of the disease.
Like JT said, what Dr. Phil says... Chalk this one up to experience. Get through this weekend and start fresh on Monday.
