Fleeting existence.
You can’t have existence without it being fleeting. Hmmmm…. Maybe this is redundant and not an oxymoron.
I will have to think about this thought a bit more.
Okay, I thought it about some more…. I have come to the conclusion that “fleeting existence” is redundant in nature. Otherwise the term nonexistence would have no meaning.
It’s a good thing my existence is fleeting, otherwise I might have too much time to reflect and become a basket case.
