#CBCGreatestGift asks, what's the best present you've received?

If someone asked you, "what's the best gift you ever received,"how would you answer?

Maybe you'd think back to a favourite childhood toy or your first pet.Perhaps the ring on your finger that symbolizes a partner's deep devotion.

While finding the right present can take time, money and careful planning, some of the greatest gifts cost little to nothing at all.

Consider the avalanche of love that landed in the mailbox of Kristian Hayes of Stellarton last summer. Kristian, aged 12, lives with autism. When his sister, Kaitlyn, appealed on Facebook for birthday cards, she hoped for a few dozen. People around the world responded: more than 3,500 cards and letters arrived to wish Kristian happy birthday.

"It's a dream come true," Kristian said when he learned of the birthday surprise. "Thank you everybody."
