@matigo That used to make my wife furious. It also made her family think I disliked them as I would always bring notes, a laptop, etc to longish family gatherings. They get it now.
It's not something you LIKE to be doing. It just happens and you grab it while you can. At least that's how it works in my case. Once you enter the zone. You don't come out for weeks or sometimes months at a time.
