Some IPs seem like they really enjoy making your life a nightmare. Talking down to you, telling you you're an idiot, making you feel like every thing you do is wrong, etc, etc. Not a lot, but I think it's human nature to remember the one that treated you like crap rather then the hundred that treated you well. Some IPs are the complete opposite.
In my short experience in the Navy but longer experience in corporate America, I've found that it just boils down to simply some people are dicks, some aren't. And it always works out that some dicks in part control your future. It's just in the Navy that you can't quit and get a better job because I haven't heard of a better one.
It's a small bump in the road and a good learning experience on how to be or how NOT to be an officer.
That said, I laughed my ass off at the original post, because those have been my checkrides almost to a T.
