The 5 year old: Mummy, is infinity for real life?
Me: Well, it’s a real concept. But it is a very hard thing for humans to understand [or at least for this human here!]
The 5 year old: Why Mummy?
Me: Well, er, it’s really difficult when you are a human being to really understand something and to explain something that never ever ends.
The 5 year old: I think the universe has an end Mummy.
Me: Ooh. That’s interesting. How does it end? Is there a wall?
The 5 year old: Hmmm. Maybe there’s another universe and then another universe and another universe until it ends.
Me: I wonder what’s behind the last universe?
The 5 year old: Hmmm.
The 3 AND A HALF year old: I know where the universe ends Mummy.
Me and the 5 year old: Where?
The 3 AND A HALF year old: just up round that road.
It’s a short cut Mummy.
