Sounds like people should cut her some slack, probably didn't know her kid was doing it.
And as far as I'm concerned, unemployed, students and kids - the people with absolutely no money to spare, should be allowed to pirate. What are you going to do? sue them for their £4 a week pocket money?
Only when they have the means to pay, and they don't, is there a problem for me.
But pirating books, and pirating music are very different.
If you pirate music and like it, you're likely to go see a concert. Books don't have this. I justify the amount of music I pirate with the amount of money I spend on seeing those bands.
They may have lost me spending £8 on their album, but they've got me spending £15 on their concert, which I'd otherwise never have gone to.
EDIT: To quote from an amazing film: "Rotten kids... You work your life out." people should really cut their parents some slack.
