Be thoughtful simply because you can.
I pulled into a service station to get my oil changed. As I got out of the car, one of the techs said, "Hey Lady, those are nice wheels. Too bad they're so dirty." He smiled, just teasing.
"I know," I said. "My next stop is the car wash." Then I went inside to wait.
When I walked to my car to leave, the tech was just standing up, oily cloths in his hand. "It took some work, but I got 'em all clean," he said. Every rim sparkled. Every speck of brake dust was gone. "Wow, that's amazing, but you didn't have to do that," I said.
"We're not very busy," he shrugged. "I had time. Thought I would make them look good for you ." Just then a car pulled into another bay so he hustled away, saying over his shoulder, "Have a fabulous day."
That was six years ago, but I still haven't forgotten it.
Instead of turning idle time into "me time," likeable people use their free time to do something nice, not because they're expected to, but just because they can.
