I lost my mom's wedding ring.
How did you lose your mom's wedding ring?
I was trying it on and it slipped off my finger somewhere.
That's awful, to lose something so important. You should be more careful in the future with other people's things.
It was just an accident, it's not a big deal.
That wedding ring is very precious to your mother and losing it will break her heart. It's important to understand how losing something of value really matters to others. Try to explain what happened and ask for her forgiveness.
