I'd have to re-read the doc to cherry-pick the examples that struck me as strange, and frankly I don't feel like giving the guy that much of a hard time - but I do remember one in particular, which is his thing about pulling out his laptop during conversation that doesn't interest/directly concern him.
Maybe I'm just old-fashioned, but if someone came to my place to crash with a laundry list of requirements and then started hacking in the middle of dinner, it'd strike me as unusual at the very least. Not to say I don't understand it; he's a busy guy and has plenty of stuff to do, and frankly it's what we'd all wish we could do when dinner conversation gets boring ;-)
I wondered if you'd meant that.
Yes, I agree. Though part of me notes that in a way, he was just a decade or two ahead of his time. The thing is, these days, loads of people do do this - not with their laptop, but their phone, whether it's texting someone, or start reading/posting to Facebook.
I agree it's unsociable and annoying - though I note we sadly can't really pass it off as rare, strange or unusual behaviour anymore, and should criticise all who do this, not just Stallman.
