Just that really.
A friend kindly gave me lots of baby toys, clothes and equipment when I had my first DC 6 years ago. I as really grateful as it saved me a lot of money at the time.
Recently, the friend has been asking for one particular toy set back - said it's of sentimental value as it was a gift from a relative of hers who died when she was young.
At no time when "giving" me the items did the friend say she wanted/needed them back. She gave them without any conditions etc.
As you can imagine, 6 years is a long time and I have periodic clearouts where I donate outgrown things to charity shops.
I honestly have no clue which charity shop I donated said toy set to. I've tried explaining to friend that had she wanted things back, then this should have been made clear at the time of giving them to me.
