Mine too! That's what my user experience with this thus far has let me to believe, too. I am thinking of creating a way to specify the delivery settings per-thread, such that messages on some threads take 3 days to deliver, or 7 days, or 14. You could have multiple threads with the same people, with different delivery durations. A core goal is to keep correspondence alive and one of the best ways to do that is to make sure enough time elapses so that there's something new to write.
