1. In the first picture, I can see two people - a woman and a man. He is wearing green polo t-shirt and blue jeans. She is wearing purple t-shirt, gray jeans and a hairpin in her short hair. I believe he is the teacher and she is a student. They are in classroom during first-aid course. There is a first-aid dummy in front of them. She is training the CPR. I think the man gave a lecture about first aid before the training. I was in a similar situation before, during safety education. It is very important to learn how to help people in a case of accident.
2. In the second picture, I can see a man. He is in a park on a autumn morning. He is wearing black jacket with orange details, black jeans and sneakers. There is a black helmet on his head. He is sitting on the ground covered in dry leaves. He is holding his leg. Behind him, there is a bike laying. I believe he had an accident. Based on the look on his face, I think that he's in pain. I've never had such an accident because I don't ride the bicycle.
