I'd guess one doesn't have to have a memorial - eg, I might just forgo it altogether. I'd rather not 'claim' the reward then put in something weaksauce because I can't think of anything I'd like.
And currently about to do some errand-hopping, then dinner making, then probably couch-flopping whilst a cat licks my face and chews on my hair. Feeling unmotivated and brain-dead today. Even gaming requires too much thinking. Heh.
Edit: oh what the heck...screw those errands. And the stack of paperwork and forms I've been neglecting. And the dirty laundry. I'm starting my couch-flopping now. Tomorrow, tomorrow, there's always tomorrow.
