I don't really know how to call this...

Anyhow... I have two objects (for example, "A" and "B") of the same type/class. I have an event (for example, "Refreshed") in both objects. Is it possible, that when "Refreshed" fires in "A", it also fires in "B"?

Edit: forgot to mention - "A" and "B" don't "know" each other.
