Who knew the simple wave of a hand could have such a profound impact?

Tinney Davidson is an 84-year-old widow in British Columbia, Canada who has waved at kids walking to and from school for the last several years. Well, the students at Highland Secondary School decided to show Davidson just how much that gesture meant to them.

The school honored Davidson with an assembly in her honor this Valentine's Day, which featured gifts and thank-yous that left her in tears.
