I just wait for the user below to die of natural or unnatural causes. Doesn't matter whichever way or whether I get to witness it or not. As long as the user ceases to exist in someway, any way, anytime, then it's fine by me.
I easily amuse myself in this dull existence will my quantum flying space walrus. After several million years, I get bored and accelerate to 18 times the speed of light, then smash through space and time and appear a few seconds after I'm banished to that land.
Unfortunately, I come out too fast and slam in to the user below tusks-first.
Obviously, you have the reflexes that are eighteen-times-the-speed-of-light good. As I phase through you, you spin and smack me with a conveniently placed redfish. Naturally, I spin out of control and go crashing in to the ground, creating a 1,095 kilometer long massive canyon scar in the landscape. I stand up from the smoking crater, wondering why I have such bad luck when I'm riding my quantum flying space walrus, and shake my fist angrily at the user below, blaming them for all that has happened.
I close my eyes and imagine myself in another place. As the cataclysmic event happens where my body is, I am now an ethereal being, transcending beyond normal human abilities. As I start to explore all that I can do, I crave a muffin and suddenly create one. However, as I try to eat it, I find I no longer have a mouth. My anger know no bounds as I throw the muffin at light speed randomly.
The muffin slows down just enough to no longer be pure energy as it nears the next poster.
