Assumptions can be a dangerous thing.
If you assume someone is acting a certain way without knowing context, you could lose a potential friend or alienate them.
If you assume something is gluten free when it isn't, you will end up feeling sick, if you are gluten intolerant. This happened to me last week and it was totally my fault. I ate tortilla chips without confirming they were 100% corn chips. My bad. Still working on the side effects but at least feeling better.
If you assume someone is a Christian, you may never talk about faith with them.
If you assume a "fact" is indeed true without verifying it, you could reach a false conclusion.
Many times we just don't know. But we owe it to ourselves and to others to find out about what is unknown. It could make a difference in someone's life. It could make a difference in your life.
Ask questions. Be curious (but not nosy). Care enough to be involved.
That's all. I'm glad we had this talk.
