We never do.
Well, there! We learned something. Oh.
History is anything that happened before you were born and is just words in a book that, at best, might be read by some people, be a question on a test, then forgotten as unimportant or irrelevant. It's why people are marching for rights they already have and trying to take away the rights others have they disagree with.
Anything that happens while you are alive is real, but when you are gone, suffer the same fate for the people that come after. The latest celebrity gossip, viral cat video, or what that bitch Nancy tweeted (I can't even!) is what really matters.
