T-Rex: I'm not going to leave what happens to me after I die up to others. What if they put on a weaksauce funeral?
T-Rex: People might equate a weaksauce funeral with a correspondingly weaksauce dude!
T-Rex: Worse, what if they bury me in an UNCOOL part of the graveyard?
Dromiceiomimus: Aww, we wouldn't do that, T-Rex! We would bury you with all the cool kids.
T-Rex: Perhaps! But I've decided to solve this problem ONCE AND FOR ALL by arranging my own funeral, plot and gravestone myself. Tada!
Utahraptor: This has actually been done before, my friend!
T-Rex: Really?
Utahraptor: Yep! It is a growing trend in the "moribund set". People get everything set up in advance! You can even visit your own grave if you want - the expiry date gets filled in when you die.
T-Rex: Spooky!
Utahraptor: Not really, since there's nothing buried there yet! It is pure FORESHADOWING.
T-Rex: Huh! It seems less cool, knowing that it's been done before. But I guess I COULD still visit my grave and pretend to be a time traveller who's changed the past! The whole "Noo! I changed the past!" idea. You know?
T-Rex: Like I'm surprised at how sucky a time traveller I am?
