All the children from this household have children, so the Grandones know "we do not talk to other people about our underwear." That works for kids.
They are all comfortable w/ Papa having his gun on. I open carry at home. When they ask we talk.
Three of the 4 shoot now. They all can hold Papa's too big gun if they ask.
They all shoot what they are able. They all know when they are able to handle Papa's too big gun, then they can shoot it too.
There were no safes when I grew up. There were no safes when my kids grew up. I have one but the son & daughter do not. It has worked for 3 generations.
