How to share someone's event on my facebook page?

[Giovanni]

Person A created an event. I am person B, and I have a facebook page. I click on share but it says that I can't share on the wall the event.
If I copy and paste the URL to write a post, and then click on POST, it says "Do you really want to reload the page"

It doesn't make any sense.

What to do?
In short: A created event, B wants to share the event within his page (NOT with his real name, but with the name of the brand he owns). Thank you so much in advance.

You can not share the events of other's on your wall.
