How to ask a deep question without it getting weird
Go first. Answering your own question shows how much to share, and it takes the pressure off. Ask one question, then follow up on the answer instead of jumping to the next one. The follow-up ("what happened after that?") is where the conversation gets good.
Questions about what happened are easier than questions about what someone believes.
A pass is a fine answer. Move on and come back later.
One good follow-up beats three new questions.
