Squish…you mentioned the stressors in your father’s time…they are (basically) the same today, but with different presentations. Those presentations are the ones that mark them apart from other times.
I think it depends more (how hard teen-life can be) on the individual teenager and his/her socioeconomic class, although generally they live an easier life today than centuries ago. This does not mean they don’t have things they deeply worry about, or that they are lazy do-nothings, it is just different.
Anthracite, I think the person who said that about your mother is a fool and ignorant girl, who I hope soon realizes she was wrong. If you want an example from my generation (I’m 19), in high school I had a classmate who went to work (part-time) when she was 16 to maintain herself and part of her family. She still had to juggle school and keep good grades in order to enter the state university, which here is one of the most selective ones. She had to quit later on her senior year because the work was taking too much time from her studies. She was confronted with a choice: either work more and slack at school, or stop working and do more at school. She chose the later one.
