do something nice for a stranger

I’ve done a few nice things of late. I’ve helped two elderly women struggling with a shopping trolley. I’ve been patient and friendly to members of the public calling to complain. I’ve organised a lovely surprise for my boyfriend.
The thing is – I’m getting so much joy out of being nice…I’m not sure who’s benefitting the most!

I want to be that person who makes someone smile. I would really like to pay for the person behind me at the toll bridge. Something like that.
