When I was a little girl (like 5-6 yoa), my grandmother explained to me that people are buried after death. Obviously, I got uncomfortable with the idea of being beneath the ground forever and not feeling anything, so she told me that a tree can grow on a dead person's burial site. I thought people could be buried anywhere (not just at cemeteries) and started to worry that passers-by could hurt me by picking at my leaves. So I asked my grandma if there'd be a way to protect me from that, to which she replied that people shouldn't do that kind of stuff with any tree...
