Good point I’d not considered.
I’m not from that kind of family, so the following never occurred to me. But …
There are extended families where intra-family obligations run deep. You can’t say “No” to any even remotely plausible request, reasonable or otherwise. And doubly so if it comes from an earlier generation.
So imagine Uncle says to commercial real estate guy “You oughta help the Weasels sell their trailer - they could sure use a break”, and now real estate guy is obligated. Even if he has no ability or connections to actually sell a trailer in your jurisdiction.
Now the good family has the agent admit that to everyone, Uncle withdraws the poorly thought out request, and everyone walks away like sensible adults. But if contradicting Uncle is anathema, or the real estate guy is passive, or passive aggressive, the only way out of trying to satisfy Uncle is by trying and failing to satisfy you.
Uggh. Wish people could park their emotions and just speak English to each other like businesslike adults.
