When someone listens, nods and smiles at every word, saying nothing, she has no idea. She has no idea what the topics are all about. All the topics. He has no knowledge at all. She’s in this thick darkness and can’t see anything. He can stumble, fall and crash.
Nothing is worse than thick darkness of ignorance. In ignorance, people make a lot of stupid choices.
Seek knowledge, find it and treasure it.
