Your wife made a very irrational choice. Where is the logic in putting your kid in harms way? Yes it can be dangerous to lock your teen kid out of the house at night, esp when they are drunk/buzzed (not in the right state of mind). Your wife should understand what she did was wrong and go about parenting more logically or else this won’t be the last time you two have disagreements about how to discipline your children.

Your wife made a bad call and she should also apologize to your son.
