Going to the beach, then, became something of an adventure. We had to pack extra clothing and hygiene products (we were all in California by then, and unlike New Jersey, the beaches there don't all have restrooms and changing cabanas). Of course, we were all well trained in the art of changing behind towels held up by whoever was with you, but after my grandmother's hip replacement, she needed a wheelchair, and that made things a bit more complicated.
An image that comes to mind when I think about the grief experience is that of a nautilus. If you visualize a nautilus or look it up, you will see that each spiral is progressively higher and above as it goes around. This is probably the best analogy to illustrate why it is normal in a grief journey at any point: to go around and around through anger, frustration, blame, resentment, disapproval, laughter, joy, hope, motivation, stagnation, and more.
Planning makes sense. It takes the stress out of last-minute decisions where emotions are often under duress.
