I was browsing V2EX today and found many high-quality blogs. One of them immediately caught my attention because it included a complete set of course notes on astrophysics. I thought that was incredibly impressive, so after some effort I managed to get in touch with the author. We then spent half an hour making awkward conversation, which led me to one conclusion: forcing a conversation when you have nothing to say is genuinely uncomfortable...
This experience taught me that I need to practice finding things to talk about and learn how to keep a conversation from going cold :)
And I should finish reading those notes.
