I wonder if your example is a different kind of trade. When we trade time in a leisure situation, we're trading something more immediate and tangible. Whereas the transactional nature of the grandparent comment is more describing something more distanced.
An example of this that was told to me is imagine you're going to dinner with the in-laws (or maybe your best friend's parents). What would their reaction be if you took out your wallet and offered to pay them cash for the meal? As opposed to offering to e.g. bring a bottle of wine or helping to set the table?
Offering to pay might be the "transactional" trade meant by the grandparent. While offering to contribute [food | labour | goodwill] is more of the trading time in a leisure situation.
Not sure that there aren't alternate pathways from "I'll take what I want" and "I'll trade you specifically this for that".
I remember reading on acoup that in agrarian societies, often they relied on favours and communal sharing in times of bounty. So say if I butchered a hog today, all my neighbours might get some. Not in exchange for something directly, but in the expectation that when I fall on hard times or they get a windfall, they'll do the same for me.
There's probably some potential for freeloading here, but these sorts of communities are likely often right on the edge of survival. If someone develops a reputation for being miserly, that might well result in them starving (or freezing) because they're rejected by their neighbours. So there's an incentive to at least appear generous and pay your fair share.
This touched a chord. For me it's a combination of both music and dance.
It's amazing to feel emotions I'd normally not want to express in everyday life and just let them flow out. Rage, jealousy, lust. The music is such a great trigger to tap into these primal feelings, and then expressing them through movement just feels incredible. It feels real and amazingly cathartic, but the transience of the experience leaves no consequences.
I guess that's why there's the saying dance like nobody's watching. Because for many people, that expression of feeling strips us down and leaves our feelings exposed and vulnerable .
I've only read one of Jordan Peterson's books - 12 Rules of Life.
Haven't reread recently, but it was interesting at the time, and sort of helpful for keeping me motivated to get myself out of a bit of a rut. What parts of his writing did you find to be indicative of abandoning intelligent debate?
