A little girl, Enna Stephens, never lost a single day to fill his house with laughter. It all happened after a seven-year tumor removal surgery on her head and she never stop laughing.

Before entering the operating room, doctors warned her parents that the operation would change the personality of Enna while. She will be more likely depressed or irritable. However, in the case of Enna, side effects of surgery are endless laughter.

her mother, Vana, 40, said, “Enna can laugh for 15 minutes at a time, or full day. When the first operation, she even giggled,” She said as quoted by The Sun.

“One time, her grandmother holding a banana and put it like she was calling so she laughed when her head was still wrapped stitches. She was laughing the whole time.

“Once she started to laugh, we laugh because laughter also something that is contagious. And, it is a great way to release emotions,” she recalls times when she awoke after the operation.

Vana, a police officer, added, “As he continues to giggle and could not stop, we took her to the hospital. There, she became hysterical.”

The boy from New Marske, Cleveland, has expressed increasingly recovering from surgery, the damaged parts of the brain controlling the expression of emotion for a while.

The father, Dougie, 44, has their own opinion about her son, “Enna was very positive. He was a brave little boy.”
