Mouse Story

by Cindy

I want to write a story that was told to me by an elderly friend just before she died. It involves a mouse who was believed to be wrapped up in a package and put in the mail. The ending to this true story is rather uneventful as the mouse was not really in the package at all so, I have told it to my grandchildren with several different endings. My "adult" friends do not seem to like any of these endings when I suggest trying to write this story. How does one pick the "perfect" ending?
