Emotional moment boy opens present his grandmother bought him before she died

This is the emotional moment an eight-year-old boy opened a present his grandmother bought for him shortly before she died.

The video shows the boy's mother handing him the present and explaining that his late grandmother bought it for him.

He opens the gift to reveal a Thomas the Tank Engine piggy bank and is so moved that he clutches to his chest and then burst into tears.

"After my grandma passed we were all heartbroken and still are," the boy's sister said.

"As we were going through her apartment, we found the (piggy) bank and broke down since my brother's birthday wasn't for another two months," she added

"My mother decided we should give him the bank at our home. His reaction had hit a hard spot for all of us since he was so close to my grandmother," she added.
