(CNN)As much of the Midwest shivered in below-zero weather this week, some people warmed the hearts of strangers with random acts of kindness.

Here are some of our favorites:

She helped provide shelter to homeless people

A single act of generosity was multiplied again and again after a Good Samaritan paid for hotel rooms to shelter homeless people in Chicago from a historic and potentially deadly cold snap.
    Donations of transportation, food and money flooded in after strangers learned that real estate developer Candice Payne had booked 20 hotel rooms at the Amber Inn motel.
    "I had strangers from social media who are now lifelong friends helping me," she told CNN. Soon, the improvised group had booked 60 rooms for more than 100 people, including children and families, Payne said.
    The group's first move was to help evacuate a tent city near the Dan Ryan Expressway, where a fire caused by a propane tank explosion forced out dozens of residents, Payne said.
    With temperatures of 20 to 25 below zero, a homeless encampment near the expressway was using heat courtesy of 150 to 200 portable propane tanks -- many of them donated. One of the tanks exploded because it was too close to a space heater. That left city officials with no option but to close the encampment and hurry to find shelter for the people living there.
