The young boy is surprisingly bright-eyed after the traumatic ordeal he's endured as a result of the latest outbreak of warfare between Gaza and Israel.
He and his parents were staying in an apartment in Kiryat Malachi in southern Israel when a rocket sailed over from Gaza and slammed into it, leaving a gaping hole in the building.
The blast sheered off several of Yosef's tiny fingers, badly wounded his father, and killed his mother, Mina Scharf, one of the first to die on the Israeli side of the border.
Yosef learned about his mother from his father, Shmuel, who is recovering in the same hospital.
Hard is putting it mildly. Doctors at the Sheba Medical Center at Tel Hashomer hospital re-attached four of his fingers, but in the end they had to re-amputate two of them.
Eight-year-old Bisan al-Aghram lost three fingers when the war came to her home.
“I heard the sound of a missile that hit. I didn't even have time to ask what happened and then the second one (hit),” said her mother, Soad al-Aghram.
When the dust cleared, she could see the bones of her child¹s fingers in small pieces on the floor.
The girl was taken to Gaza's al-Shifa hospital, but it was too crowded and couldn't give her the best care. So the family asked Israel for permission to cross the border.
Initially, her mother was terrified at the prospect of people considered an enemy in her country handling her wounded daughter.
“It¹s a strange situation and it's my first time entering Israel. I was afraid, but they treat me and my daughter in a very nice way, and I understand that medicine has nothing to do with politics,” al-Aghram said.
That's the philosophy the hospital tries to adhere to — no matter what.
The same doctor is treating the two children of conflict who both lost fingers from rocket blasts.
