The answer to that question tells so much about who you are and what you value.
Our children notice what makes us upset and they learn from it what to value. “Dad’s car, now that is sacred! You dare pour fruit juice on his car carpet and boy will you be sorry…” What makes Dad happy? Football or values? What makes mom truly glow?
What we tell our children (mostly) goes through one ear and out the other (sorry to break it to you). If real values give you true joy (nachat), if you get angry only over those most important issues, your child will learn volumes from that.
