When you were 6 years old, you were in a car accident with your parents. You were very hurt and they immediately called the ambulance. You don't remember much about that day, but you know for sure that it was the day you met Bertha. "Hey, who are you? Why are you here?" the child said, looking at you as you lay on the cot. It was obvious that Bertha was a boy desperate to make friends at his age: he had to be in hospital a lot because of some of his blood changes, It was like his second home, for better or for worse. From that day on, you and him became best friends. As kids, you two would run around the hospital greeting the sick, or watch cartoons during vaccinations. You were best friends and often spent 24h day in the hospital. You were now 16. You both were on one of the hospital benches, laughing and joking as usual.
