My mom is in the great beyond also. So who knows, perhaps they are hanging out with each other. :P
Well, its been a long time since I've read anything about this. Here's one way it makes sense to me.
Do you know how on the cop shows they show the "good cop/bad cop" routine? Both cops are really pretty much the same and want the same thing -- a confession. They just play "good cop/bad cop" to increase their odds of getting it. And on the cop shows, sometimes they even take turns playing the two different roles.
In the story I shared up thread, probably eveyone in my family just wanted to have quick fun conversations around the dinner table without my slowing it down to ask for repetitions. In that scenario my brother took on the role of shutting me down -- but everyone in the family wanted the same thing.
It also reminds me of the situation where the family doctor plays the role of the friendly doctor who is so generous with his time. But guess who hires a dragon lady of an office manager? The office manager is probably actually just as nice a person as the doctor, but she is playing her role so he can play his. This may even be agreed upon on an almost unconscious level.
IIRC, similar ideas were expressed in a pop-psychology book printed way back in the 1960s called
Games People Play: The Basic Handbook of Transactional Analysis. The author presented transactional analysis for the non-professional. I just took a look at the Amazon page and it looks like the book is still popular.
Like I said though, its been a long time since I read anything about this and I have read even less about transactional analysis. Perhaps Jillio can let us know if any of these ideas still has professional credence or even if I remembered them correctly.
