The son couldn’t just say ‘hey dad, you didn’t open my gift’. If they had a good relationship, that’s what he would do, or just get it from under the tree and give it to his dad. When the dad found it, he didn’t call his son down and say ‘oh I missed this one son, let me open it with you here’……they’re .dysfunctional and not comfortable with each other. When your kids are teens, the relationship falls mostly on the adult to model good behaviour and communication.
Mu children are perfect to us, yes. 😉 They can communicate openly with us and don’t get nervous around us, that’s not really being perfect. It’s just the basics. Really basic actually as you’re in trouble. Sorry if you don’t see that.
