Earlier quoted context omitted.
I don’t see what the problem is. If you have helped someone a lot, and then call in a favor and the ghost you, you didn’t lose a friend. You lost a parasite. It’s like when you lend money to someone and they avoid you to never pay you back. Depending on the amount that can be money well spent.
> I don’t see what the problem is. The problem is the transaction is unbalanced. They got help when they needed and refused to help when called upon. Someone took more than they gave and there's no real way to address the issue so the only sensible thing to do is to avoid putting oneself in such a position in the first place.
It's also hard to measure one's contribution in a relationship (hey, maybe they were a really good listener; or maybe they can't find time to help you move, but when your kids get sick, they'll move the world to get the best possible care for them?), so let's not go and introduce quick-and-simple rules for what definitely are relations on a case-by-case basis.
