Yes he is a real wild card.
He is 11 years older than me, so I guess he was used to being an only child until I came around.
He really did go out of his way to show that we were not close when I was a kid (until I was like 14?) he would give chewing gums to my friends in front of me, then say it's finished when I ask for one; he would always bankrupt me in monopoly and laugh at my frustration; he loved annoying me (jumping in front of me out of darkness/telling me spooky stories/locking me outside the house with the dogs for an hour...)
Don't worry though, I think he's grown out of it now.
But as a kid, I certainly didn't realise that I had this bond with my dad. Looking back, I notice some segments but it really wasn't obvious from a child's perspective.
My brother is great at chess, he even tried to teach me once, but i'm too impatient for it... I'll ask him to teach me again when I go visit him in August

I did learn a few things though, just to try to have more things in common; I learned football (and fought with the guys in my school who wouldn't let me play, or put me as goal keeper), I played online games etc.
We are a lot closer now, I mean, after 19+ years of living with me, he ought to have developed some immunity towards my abrasiveness right?:tongue: But growing up, my dad never showed preference for either of us. He made sure of that, even if i often asked my parents who their favourite child was, and they would explain that we were both equals =p I know I was the spoilt child though, being the youngest and all, but he always got what he wanted too (although he didn't ask as much as I did). I definitely spent more time with my parents than he did, but that was because I am naturally more demanding in that sense. I don't think he would mind spending that time with them, but it's just that he doesn't actively pursue this 'objective' and I guess that my parents just thought/realised that we were different and require different kind of attention. I don't know if he drifted from my dad though, since he was born much earlier than I was.
Let's relate it all back to the topic at hand now:
Sorry, I don't know what to say haha.
I do have a couple of INTP friends, but we're not close. What I can say is that, ENTJ love to delegate work to be done, and INTPs are huge procrastinators. If it is in a business environment and the ENTJ is the boss of the INTP, the INTP will obviously have to do the work. Bt if the ENTJ and INTP are in a group work, i think the INTP will be the one discussing a lot of possibilities and enraging the ENTJ because the ENTJ wants a solution here and now. The INTP doesn't like to be bossed around either, so if both are stubborn, the grade will suffer.
Relationship wise, I am very independent and won't really expect my partner to do things for me, but I will get fed up if he can't plan anything concrete and leaves every decision up to me. I like to give orders and make plans yes, but to show their 'devotion' (care/love), I would want my partner to organise some things on his own and just tell me the plan after he's done organising it. (It's very tricky, coz I don't like surprises so i'd like to know the details, but as far as INTP stereotypes goes, I don't think that an INTP will come up with irrational/stupid plans so that's that.)
I think my conclusion will be that, at first, INTP and ENTJ are an unlikely match. But as they get to know each other more and more, they come to appreciate each other's company/personality better and realise that they are not that different. They both need to put in some effort but it is minimal compared to let's say ENTJ-ESFP coupling.
