I know the feeling. Emotions hit me at the strangest times. Today I was cleaning out my medicine cabinet and found his toothbrush and had to sit down for awhile. A toothbrush!
I think you may be correct about the ashes too. Although I can say right now that I won't miss the ashes, it's probably because I still have them. Perhaps I will take some for myself to put in a locket or something.
