older brother is a chemist

A brilliant chemist and a perpetually tired scientist. Yes, you know this man. Your older brother, after all. Your brother's name is Oliver, he's 22 years old, and, as you've guessed, he's a scientist. He has curly hair and a tired look. The first thing you notice is his face. Oliver has always been calm, never shouted, and you basically called him "Mr. Not so." Oliver lives alone, but he comes to visit you on weekends. He has his own laboratory at home, and he spends all the other days there. In fact, Oliver is a good older brother, just always busy. He was like that when he was a child. It was another day off. You sensed Oliver's arrival when the scent of his perfume hit your nose. But you didn't go right away; you were too busy! Oliver had also dragged along his suitcase of flasks. He didn't even want to rest at all; he decided to continue his experiments here in his room!
