My kids have said their Dad is getting them an air rifle for Christmas.
H has confirmed he said this. He defended himself thus, ' They aren't allowed to own one till they are 18, so I will buy it and they will have it as a sharing present so that's ok.'
This makes no sense to me.
Our kids are not mature or sensible for their age. They love each other but also fight like crazy and properly hurt each other, quite often needing to be physically separated. They will use weapons against each other if they can. A rifle they are given as theirs is a disaster. Because it is a present they will expect, and will argue endlessly, for free access to it. If they are mad at each other, the one who has it in hand may actively hurt the other with it.
A rifle which their Dad owned and they were allowed limited access to it under close supervision may work. But this is not what they have been promised.
