A girl that I'm close to lost her stepfather a few months ago. He was beating up her mom every day; one day her mom told him she'll leave, he got drunk and shot himself in the head. If she wouldn't tell me, I wouldn't even know this happened. She loved her stepdad, but took the loss and moved on. She also has a business, an online lottery that she manages with her family, she actually makes money. She's 20 years old. She took a massive loss like it's nothing, kept it G and moved on with her life. Who's stronger?
