The distance of time

AV Club takes a look at Ranger In Time, a series of children’s books about a rescue dog travelling in time to help in disasters, which drew some controversy overnight with someone flagging up the new book about 9/11.

Author Kate Messner responded that it came from her audience asking - kids born after the event.

Those kids were born years after 9/11 and don’t have the memories we do as adults. To them, it’s an awful thing that happened in history, like Pearl Harbor is to many of us. They want to know more about it, but adults don’t like to talk about it. So kids are left wondering.

It will always be too soon for me, but it’s true. Where do we draw the line, and when does it move?
