Small acts of kindness can go a long way.
For example, someone can snap a picture of said act and post it online, where it will go viral and be seen by hundreds of thousands of eyes.
That's what happened after someone captured a telling photograph at a subway station in Atlanta, the Daily Mail reports. The snapshot, reportedly captured in the city's Lindbergh Center, shows an elderly man teaching a young stranger how to tie his tie while waiting for the train.
The story behind the photo is that the older man's wife spotted the younger man sitting on the bench, struggling to get the tie on correctly. She then encouraged her husband to "come over here" and help him.
Wearing a fleece and flat cap, the man happily obliged. The moment was captured and uploaded to Facebook by Redd Desmond Thomas.
"The young guy sitting down was struggling with his tie," the bystander explained in his post. "The woman in the red coat noticed, and asked 'Do you know how to tie it properly?' The young guy said 'No ma'am.'"
He continued, "She taps her husband and says 'Come here and teach this young man how to tie his tie.' The older gentleman moved without hesitation and game him a step-by-step tutorial; then afterward the older gentleman watched the young gentleman repeat the steps and show him that he had it."
