From facebook:

A man was in Hallmark buying his mom a Birthday card when he noticed an old man standing in front of the Valentine’s Day card section contemplating which one to get. He decide to go over and ask them the man:

“Are you getting a Valentine’s Day for your wife?”

The man then replied:

“No my wife died 3 years ago from breast cancer but I still buy her roses and a card and bring them to her grave to prove to her that she was the only one that will ever have my heart.”

Happy Valentine’s Day
