Wanda keeps asking about what to do.  I tell her I really don't care, as I won't be present.  

When she presses ( and we're 80, so its probably time to get serious), I tell her to cremate me.  It will get me accustomed to high temperatures.

Then, she can keep the urn on the mantle, or somewhere convenient.  

When she thinks of something I did wrong, or forgot to do, she can simply grab that urn, walk to the toilet, dump a little in and flush.  "Take that, you worthless &*$%".  And she will always have some left for next time.
