but it sounds like work to me
Of course, it was yes. But it's enjoyable to do, the work itself and the result of it. To me that brings satisfaction I guess. I relax too, though.
Sunday sleep-ins are awesome, I do it most Sundays, although a sleep in to me is only about 07:30-08:00 as I get up earlier on the week days. I hope you found some pleasant surprises in your day.
