Invent a memory of me and post it in the comments. It can be anything you want, so long as it's something that's never happened. Then, of course, post this to your journal and see what people would like to remember of you, only the universe failed to cooperate in making it happen so they had to make it up instead.

And just to make you work for it, RPed incidents count as "happening." You have to make whatever it is up on the spot.
