answer:I would probably call my friend and just casually say, “Hey, did you know you got a parking ticket when you were using my car?”, and take my cues from how the conversation goes from there. Most likely, they’ll do the right thing and pay the fine. If they don’t offer to pay, and the fine isn’t too much, and it’s a really good friend then I’d just pay it myself. If it wasn’t a good friend, I’d ask them to pay it.
