It wouldn't be polite just to start talking without a proper introduction. I'm Jack. Welcome. It's a tendency of mine to explain things in such a way that they become a bit clearer than before. Things become more understandable. I can take the parts of a problem and dissect them into their particular parts, slap some comprehension on them, and serve them up proper.
If you've got a question, ask. If you've got a story, tell it. I may just impart some wisdom.
