Alonzo Mourning's good deed

I read the following online this morning concerning former NBA star Alonzo Mourning...

Mourning's vehicle had been sitting in traffic on the right lane, when he spotted a disabled person sitting in a motorized wheelchair along the curb. Mourning jumped out of his SUV, stood in the road and stopped traffic by raising his long arms, while the wheelchair-bound pedestrian made it to the median. Then, the seven-time NBA All-Star immediately went to the southbound lanes and raised his arms to command stunned drivers to stop. All traffic movement instantly stopped, and the wheelchair safely made it to the other side.
After making sure the citizen was safe on the other side of the road, Mourning lowered his arms and headed to his SUV to the sound of cheering fans, who recognized the 6-foot-10 temporary crossing guard.

Alonzo has a reputation for being a fierce competitor on the court and a giving humanitarian off. I wonder how I would have reacted in the same scenario.  My guess is I would have been late to whatever my destination might have been and impatiently waited for the light to turn green so I could speed off on my way. 

John Wooden famously said a person cannot live a perfect day without doing something for someone with the understanding they could never return the favor. I don't know how Alonzo lived the rest of his day, but helping this person across the street was the perfect act of kindness in that moment.

What will you do for someone today without expecting or earning a favor in the future?
