Me and ENTP Guy:
It was full throttle and active in a good way. He kept me on my toes and I proverbially smacked him around for good measure. We had to be in our finest form at all times (not because we required it from each other, but because we were placed in competition by the powers that be). He would tease me constantly (when he wasn't terrorizing everyone else

) and it was a great adventure every day. He'd come cruising in late most times, and harass me on his way by. I made sure to lob a few choice words at him. It was our routine.
Trouble with him was he could make a fiend of a saint, tax anyone into a state of "One more word, boy, and I'm going to kill you". Which was a pain. Once he managed to work me into a state of tears (I was having a horrible time at home) and the minute I didn't come back at him, didn't retort, didn't verbally kick his shins, he came apart. I could NOT have predicted that reaction. I was stunned.
Deeply depressed, I had stopped speaking for several days (my life was really that bad and dismal at the time, I just couldn't speak anymore) and it drove him insane. I remember my partner Rob saying to him "What did you do to your girl? She hasn't spoken a word..."
After doing anything and everything to get a sign of life out of me, exasperated and anxious, he finally wound up throwing his tools down and cornering me between two marine engines. He was in the process of attempting to drag my half-dead self out of my shell when one of the diesel engines nearby went into a "run away" state (SCARY!) We both froze and waited tensely. The emergency passed. We were both so giddy at not having died that whatever was wrong just went "poof" and he spent the rest of the day picking on me and being very affectionate. I was acting like "pink" again. I think he was relieved?
Too bad about him... I would have done just about anything for him.
