Give it time. That kid will not forget your day of shooting. The fact that his mother is against it will probably make it all the more appealing to him. If he is like most boys he will bring it up every chance he gets, she will get sick of hearing about it. Fat chance mom will get that kid to lean liberal when Grandpa leans the other way. Most boys idolize Grandpa and their beliefs, not mom. You will get the chance to teach him how to shoot again, just a matter of when.
