Lighter topics, lighter topics. I don't have a problem speaking about Zeqing the person eventually, and indeed I think we MUST speak about it at some point if we continue to interact with him, but the 'first date' isn't the time to talk about how your 'mentor committed suicide and left her kid for you to raise'.
I'd rather keep this fairly light for now so we can learn more about the man himself. We know some things about him but its honestly not enough to make any kind of long term decision yet.
