Irena Sendler died today. She is one of those largely unheard of heroes. She is someone who did something heroic on a massive scale and in an ongoing effort. She rescued 2,500 children from Nazi concentration camps and almost certain death.
For every one of those children she risked her life. Imagine risking your life 2,500 times. Imagine knowing something was wrong and acting against it every day despite overwhelming risk to yourself. She did that and then went on with her life as if it was no big deal.
