We have one rule: he doesn't use the chainsaw unless I am home and aware of it.
Just got home fro shopping and he's been using it. There were 3 DC home aged 8-12 but none of them were aware either, and even if they had what were they to do except watch him bleed out before an ambulance could get here?
So AIBU to
A) hide the chainsaw
B) let rip at him for stupidity?
