One aspect that probably plays a role: I'm feeling good because I kept busy, but I've been pretty isolated due to an extended health issue (heavy metal poisoning) that takes loooong to recover from (but it works fine thanks to chelators), and I deliberately work a low-paying job from home. While I'm not an extrovert I'm no introvert either, I enjoy talking and even presenting and got very little of that the last few years. So the reason I go to the coffee shop is - people. While I don't talk to anyone (because that only very rarely works here in Germany) somehow just being in the crowd feels good, it satisfies some deep desire. Somehow merely having "noise" at home, even if the source is people, is not the same. The brain is not that easily tricked, it knows the context. It's more complicated though since having people talk does help even at home, but it's different, different brain circuits are exercised, it's not a replacement for the 2-3 hours in the coffee shop.
