Sometimes I just crave talking with someone about what I am working on. If I am designing something I can't just call the people that do fabrication on my team because they are busy working on the last thing I designed. We're so asynch and efficient that I hardly ever talk with anyone about my task at hand so I spend a lot of time staring at the wall above my screen, second-guessing myself because I can't thrash out decisions with another mind.
Then I end up browsing HN for a distracting but familiar endorphin hit....
