How do you teach forgiveness when you're angry?
My 10 year old son deliberately destroyed something his sister made and I lost it. After I calmed down I realized I had just shown him the opposite of what we've been teaching about forgiveness and reconciliation. We talked through it and I apologized for how I handled it, which led to a really good conversation about how even dads mess up and need to ask forgiveness too. I think sometimes our mistakes are the best teaching moments if we handle them right.
This is one of those parenting moments that separates the good dads from the great ones. Modeling that apology and forgiveness shows your son way more than any lecture would.
