Really--I'm a SEP (Somebody Else's Problem) A person's natural tendency to ignore things they don't easily accept, like, for example, aliens at a cricket match. Any object around which a SEP is applied will cease to be noticed, because any problems one may have understanding it (and therefore accepting its existence) becomes Somebody Else's Problem. An object becomes not so much invisible as unnoticed, so just ignore me. I promise I wont gank you.
