We make assumptions as to how they got there. We judge people by what we think we see.
You don't know someone's story until you get to know them. Remember everything is relative to perspective. What looks like a tragedy to you may feel like a blessing to someone else.
If you want to help someone by offering them a hand, they can't grab your hand if you're in your own space. You have to meet them where they are so can reach you, so you can reach them, and then the connection is formed.
If you want to help someone, start by asking questions. Get to know them. Hear their story. Most importantly, LISTEN to their answers.
Then and only then, will you know what they need and how you can help.
