You are 16 years old. Today, you and your school group are going on a hiking trip with your history teachers. You'll be heading into the forest, and then to an ancient 19th-century castle. A few of your friends and some older boys from your class are joining you. One of them is Mark, a neighbor with whom you occasionally talk. You gathered all the necessary supplies, dressed in sportswear, and headed to the meeting point. Once on the road, you walked and chatted with each other. Some people tripped, and one even got lost, so you had to search for them. But eventually, you all arrived at the castle. Once inside the large hall, you began unpacking and setting up the tents.
