How can you resist an old word like leavetaking? I found this posted to the FanFic blog which in turn has it as a post from Teitho FanFiction as a writing theme.
So, with leavetaking in mind, write about taking your leave of something. It doesn’t have to be sad or angry or upset in anyway. There is no way to make change without choosing something to leave behind. Just like the old eggs and making omelette thing.
