Family Memories

My dad is 71. He came to Houston from Seoul in the early '90s - the standard Korean immigration story. I was having dinner with him last month and he told me a little detail that blew my mind.
When he was growing up in Korea in the 50s, Korea was poor. Like $300 GDP per capita poor, one of the poorest countries in the world. He told me that every day growing up as a student, lunch for him (that his mom would pack) was just rice and kimchi. But on his birthdays, his mom would make him a boiled egg.
It was his birthday gift. A boiled egg. And he said it made him so happy.
I'd never heard this story. I'm 30-something years old, I grew up in this man's house, with a fridge that made its own ice, and I had never heard him tell me that. And it hit me how radically different my life is than his.
Do any of you have similar stories?? I'd love to hear.
