If he could, Severus Snape might choose something like this:

But as an experienced spy, he would never blow his cover. ;-)
It's May 2nd, eleven years later, and somewhere in the world Severus Snape is leading a quiet life, enjoying his freedom, and not giving a flying hoot about the Wizarding World he left behind.
...because Afterlife is much more interesting when it takes place on this side of the veil.

I think he'd go with 'BRB, don't wait up'
thick-skulled Gryffindorspeople who would not so much as question the absence of his body and "bury" him anyway!"... makes me want to write a story about Severus watching his own funeral, a la Tom Sawyer. ;-) But it's probably been done by now."
