You made me do a little thinking, my mother was not quite nineteen when she married my thirty-one yo father. He owned a restaurant at the time and she was a young farm girl who started working part time for him when she was sixteen.
You are blessed to have such parents.
Our frame of reference is so skewed these days, with couples marrying later and later in life (or not at all) and recent generations promoting the nonsense of “perpetual adolescence.” The concept of adolescence was practically unknown until the 20th Century. A person of 16-18 years of age was considered an adult, and even today perhaps should be. I went into the Navy at 17, and have been making my way in the world since, some 45+ years ago. We need young adults to once again begin acting like...well, adults.
