Real case education
If that scar was left by an accident, please share that experience with your children. Teach them how to stay away from potential dangers with real cases, and remind them to put sharp objects in safe and inaccessible places to avoid unnecessary injuries.
Heroic deeds education
If that scar is a witness of your heroic rescue, it is even more a medal of merit to be proud of. Share your heroic deeds with your children and teach them how to lend a helping hand to those in need within their power. Let them know that everyone's small efforts can contribute to reducing the harm of vicious incidents.
