DD is 5 and home schooled. Right now she is learning about community helpers. Today she was instructed to draw a picture of herself as a what she wanted to be when she grows up. She drew a picture of herself as a Marine (dad is a Marine, served three overseas combat tours.)... No problem right? Except then she added a gun.
Now, when her father has deployed, we always explained to her that he was leaving to fight the bad guys. At her age that was best for her. She asked questions such as how he will fight them, what he will use, etc. He told her that he had a gun to keep him safe because the bad guys also had guns.
She knows gun safety, that some people use guns to hurt people to be mean, and some people keep guns to protect them against bad guys.
I am sure I would get a phone call if she did this in public school =/
