Woman doesn't have to cry over spilled milk after kind grandma saves the day.

The story of a woman who identified herself only as "a grandma" and the sweet thing she did for a harried mom of two young kids on New Year's Eve is going viral because it illustrates how much it can mean when one stranger is nice to another.

In a post on Facebook (later posted by huge Facebook group "Love What Matters"), Kristin Sherman explained that she was shopping at a Meijer grocery store in Michigan on New Year's Eve, trying to purchase a few things (including milk) and get out of the store before either one or both of her tired sons had a total meltdown. Afterwards, while putting her groceries into the car in the parking lot, the carton of milk fell and broke open, spilling everywhere.
