@ljs Sorry for what you had to go through.
Reminds me of my parents' lives. It hasn't been long since the quality of life in South Korea greatly improved.
My father and mother couldn't even finish high school because they had to work to support their family.
They tried their best not to make me (and my sisters) experience the same thing. I am always thankful to them.
These days the situation is much better. Many people are not forced to work and give up studying. And on the internet you can find most things you need for studying something.
