My teacher told me once about a true story, where an 10 or 11 year old kid had brought a pr0no to school. His teacher found out and aprehended the movie.
Some time later, the parents go to school furiously, going like "why the hell did you take our film!?"
And they talked. Turned out they weren't angry about being a pr0no! They were mad, because the kid took the movie without permission and because the movie was rented, and they had to return it before the rent price went any higher. XD
It all depends on the family. Some don't mind (like the above), others will.
