I'm thinking of keeping my best friends deceased wife's ishuffle
How did you get the ishuffle and why do you want to keep it?
I stole it from my best friend's house
You need to return the ishuffle to your best friend because I am sure he would want to have it. You have stolen something that you have no right to have. Your best friend may not forgive you if he finds out you stole from him.
He's made a new ishuffle and it's great.
It's possible that your friend had to create another since the one that he want was missing. It's wrong to get something that may have deep sentimental value to him. You should return it to his home.
