<human>: Could you distill the essence of the text into 1-3 sentences?

When I was little my friend had just gotten an awesome new toy (a little cat figure and its house) and I loved playing with it.  I was playing with it at school and I forgot to give it back to her before she went home for the day.  When I got home, my mom asked where I'd gotten it and I told her that my friend had given it to me, and never gave it back.  For years I thought I was such a horrible person, that I was going to go to jail for stealing, etc.  I got a huge wave of guilt every time I thought about it and I kept putting off admitting to it.  Obviously years later I realize it wasn't the life-ruining crime I thought it was.
<bot>: friend let me borrow her toy.  told mom it was mine and didn't give it back, i thought i was basically a felon.  later realized not that big a deal.
