Our safe would be kinda hard to miss… yes, they know. The great grandbaby is six, she’s got the gun safety thing down but its going to be a while before she gets access to the safe. Still, it’ll probably be well before she gets to start dating at the age of 30.
I have a 15 years old daughter and twin girls that are 7 years and all 3 know exactly where the safe is located but only the 15 year old my wife and I have access to the safe for now. I constantly teach my kids safety and the dangers of firearms if not used properly or placed in the hands of evil people.
I have three safes (separate for firearms and ammo) in our house. My 17 year old know how to access the safes and use the handgun safely.
My babies are a 26 yo girl now an attorney in Chicago and a 24 yo Marine now in college in NW Ohio. He knows the combinations. She doesn’t care to. Both are trained, him more than her.
