Last month, a 90-year-old man in Wishek, North Dakota named Harold Krueger lost his wife of 63 years. And he's still dealing with it. But one of his daughters helped cheer him up in a pretty amazing way.

Before she passed, Harold's wife LaVina was planning to throw him a big 90th birthday party. So his daughter Debbie took over the planning. But she also ADDED an idea.

She wanted to see if she could lift his spirits by talking about him on Facebook, and asking her FACEBOOK FRIENDS to send birthday cards.

Now, Harold is a decorated World War Two veteran, and also served in Korea AND Vietnam. So it wasn't a hard sell, and her friends immediately started SHARING it.

Then this past Sunday, his daughter posted an update to announce Harold has now received over a THOUSAND cards from people in 48 states. And every morning, he goes to the post office at 9:30 A.M. to pick up even MORE.

Harold says the cards that have cheered him up the most are the ones from elementary school kids, thanking him for his service.
