When you read 70 pages of this thread.
When you go to great lengths to psychoanalyze every character, and spend months thinking about them to understand them. (And posting write-ups.)
When you evangelize (appropriate wording, no?) Evangelion to people irl and online.
When you ask a (~80-year-old) piano player to play Fly Me to the Moon, and you are in absolute heaven. And then you TELL HIM where it's from, and get him to learn Thanatos as well.

I've been turning NGE over in my head for months, and I still am not entirely sure of everything going on. It's nice to have a show, that you care about enough to think about it so much. Plenty of fiction is deep, and esoteric, but not worth investigating. NGE, is the zenith of all fiction.
When you compare every work of fiction to Eva.
When you find Eva references everywhere when watching anything involving Gainax alumni (TTGL, Kill La Kill, etc.).
