For me, most people in my family are in better shape financially than I’ll ever be. As for friends, if they ask for a favor and it’s do-able, I’ll do it. For example, if someone at work says they left their wallet at home and they need lunch, I’d offer and then I’d expect that within the next week or so, they’d pay me back or buy my lunch. That doesn’t happen very often but that’s an example. If they didn’t pay me back, that would be the last time I did that. If someone needed a ride, I’d do it if it was something I could swing. If they needed multiple rides on multiple occasions, I’d say no.
I offer to take my friends’ kids out with my daughter, and I pay, and don’t expect repayment because that’s just what we do when we take other kids out – we pay. Then the other moms reciprocate or they may reciprocate by having my daughter sleep over or something – it all works out. Most things I do for people, I do voluntarily (like if coworker left their wallet at home, I’d offer to buy lunch without being asked).
I’ve loaned money to friends, one example is a friend borrowed 20 dollars and I never saw it again. Another friend borrowed 6000 dollars in cash to put down on a new car, and I was nervous because she’s one of my best friends, and I knew if she didn’t pay it back, I’d not only lose 6000 dollars but I’d also lose my best friend, but she paid it back within a few days, as agreed (she was waiting for a loan to be approved by the pension system, and she needed to put it down on the car asap).
I had to think about examples because I don’t get asked for favors a lot. A relative who lives nearby asked me to drive him to pick up his car at the mechanic once, and asked to park his truck in my driveway once, all easy and do-able. Stuff like that is what comes to mind.
