My duty as a grandparent doesn’t include indulging stupidity.
I think it’s pretty insulting tho say that working in a war zone is stupidity.
And besides, if an adult son or daughter is working in a war zone because of their mission, their mom is not going to be able to do anything to get them to abandon their objectives because of personal danger.
I’ve certainly learned that a parent can’t script-write or stage-manage their adult children’s lives.
