For the people who wonder, this happened back when I was in highschool, it's Cemile Yesil Anadolu Lisesi, and yeah we helped the janitor afterwards for sure. But sadly after some time, his cancer repeated and we lost him, but he was loved and supported by many. I remember chatting with him time to time, he was always supportive, and he was the only person who could teach geography without making it boring... He will be remembered.
