2 from my mother in law:
She wouldn't take a knife from your hand, you had to lay it down and she would pick it up. Something about cutting your friendship was the reason.
Everyone in your group had to walk around the same side of a post/bollard/pillar or you would end up in a fight with the person who went around the other side.
She's gone now but lives on in my wife still does the post/pillar thing. I go along to keep her happy.
