Everything is a bucket

"What is a bucket?"
"A bucket is a container that can move liquid from one place to another."
"But what really is a bucket? Is a mug a bucket?"
"Well, yes it is. A mug is a small bucket made out of porcelain."
"What about a tractor? Is a tractor a bucket?"
"Yes, of course. Why would you even question that?"
"Is an envelope a bucket?"
"Why, yes."
"Is a mother a bucket?"
"Uhm... Well... She carries a child inside her for 9 months..."
"Is a room a bucket?"
"Of course, you can fill it with water. Everything is a bucket."
"How come everything's a bucket?"
"Life works in mysterious ways, we all carry something to the end."
"Are you a bucket then?"
"No, I am just a disembodied voice. I have no form."
"How come everything is a bucket except for you?"
"You aren't a bucket either. If i deleted everything in the world, only you and I would stand left."
"Okay, what about the reader, the one reading this story. Are they a bucket?"
"The reader... That's up to them. I don't know their form, because the reader can be whoever they please. We can't see them, but they can see us."
"If everything was deleted right now, would space still exist?"
"Space is like an infinite hole, or more likely, an infinite bucket. You cannot delete infinity infinitely, because then it would be deleting for infinity."
"Is time a bucket?"
"Yes, it has a start and an end."
"But when did it start?"
"An infinity ago."
"And when does it end?"
"In an infinite."
"So, is infinity a bucket?"
"Infinity is infinity, and infinity is not a bucket, but infinity can be inside a bucket."
"Well, then a bucket must be a bucket then, right?"
"No."

The end :)
