I'm going to return someone's ID that I found on campus.
Why do you want to do that?
It will be an act of kindness. I do not want to cause any harm to any person, and I will feel really bad if they don't get their ID back.
It's really nice that you want to return their ID. You're doing the right thing.
Thank you, I feel happy about that.
I'm glad you're happy about it. It's normal to feel happy when you do something nice for someone, like return something that they've lost.
