Sometimes, the most important lessons are learned outside the classroom. These students were taught a valuable lesson about compassion when they least expect it. 93-year-old Louise Edlen had been waving to students for the past 5 years as the school bus passed in front of her house. The woman has problems remembering the names of her loved ones, but she has always remembered to wave at the children passing by. Until one day, when she suddenly stopped. The kids noticed she was no longer sending her usual greeting and found out the woman had had a stroke. So they reached out to her and did something truly hearth-warming! Watch:
