Prepare to get chills.

This Facebook post of an older gentleman coming to the aid of a younger man struggling to tie his tie while waiting for a train in Atlanta has gone viral.

It's not really hard to see why this picture has connected with people. It's a small act of kindness and those prove sometimes the smallest things can generate the biggest response.

Maybe this can serve as a reminder to go out of your way and do something nice today for someone you don't know. Consider this a challenge.
