Ugh.
Had to deal with my sibling calling me a murderer cause well I made the mistake of telling my parents I killed the squirrel.
So I did the only thing an overly mature, angry at her siblings attitude me does.
Sent her a pic that my hubs took when he shot three rabbits and two squirrels in one day.
Your sibling has a good heart some people feel even small lives matter and have compassion and mercy on all Gods creatures.
I wouldn't be to hard on her/him. They seem to be far and few anymore.
