to score a little milk of human kindness

[Silverobama]

Hi,

Those that liked candy more than crackers were more likely to volunteer around campus or for additional studies. So if you’re looking to score a little milk of human kindness, try putting out a plate of cookies.

What does the red part mean?

Thanks a lot

"The milk of human kindness" is a phrase from a Shakespeare play. Macbeth, I believe.

As the first sentence stated, people are more likely to volunteer after eating sweets. So if you want to get people feeling generous, ply them with something sweet like cookies.

The author is trying to play off of "milk and cookies". Put out cookies, receive "the milk of human kindness" in return.
