Catch! Let me give you some examples involving technicalities:
Example 1. You let me drive your car, and I crashed it into a KamAZ truck at full speed. I was at fault in the accident. Afterwards, I told you that I wouldn't compensate you for the damage. And you wouldn't be able to force me to repair your car through any court.
Example 2. You let me drive your car again. I got drunk and drove. A traffic cop stops me. Afterwards, you lose your driving license because you entrusted your car to a person who was intoxicated. I, of course, also lose my license, but it doesn't make things much easier for you.
Example 3. Dreamcatcher came to visit me and said nasty things to you in my name. Do you think I'm to blame?
It's unlikely that Dreamcatcher would say nasty things to me :) But in any case, you are not to blame.
