I already have a spot to rest.
I didn't care about doing this so early, but Mom wanted to get all of her arrangements done and paid for, so I went along. She spent a lot of time designing every detail about the marker (the permanent mom/child protective embrace and the permanent flowers when there will be no one left to bring real ones). This must have been in the early 90's. Mom is now buried at the stone and there is a place inside of mine to stuff my ashes. I'll probably have some scattered somewhere as well.
At the time, some people thought this was creepy to do so much in advance, but I like already having a little statue to myself.
