Hahaha. I wouldn't say I identify with that last part, but I really did identify with the Ep description too. I've also noticed lots of similarities between the Ej description and Ejs I know, although I'm not sure it's a case of "all or nothing." I haven't interacted with enough Ijs to give my mind on the Ij descriptor. The part about Ips shirking their duties made me lol.
I don't particularly care for the "how to spot" section though. I walk quickly when I need to, and don't when I don't.
