Immediately the movie "50 First Dates" came to my mind and I had to laugh. In some ways the main character got do this over and over but she didn't have the memories of the day before...
In some ways, in some instances wouldn't that be nice? Nice to just be able to forget all the pain you felt the day before, all the sadness, all the anger, all the bad things?
But then again I guess if you forgot those you'd also miss out on the wonderful things too! The hugs, the love, the joy.
I guess we really do have to take the good with the bad and you know what? I'm good with that! Because the bad makes the good even better! It helps us to be more grateful for the good... at least it should.
