Cub: Hey Mama, what's that?
Me: That's an ampersand, honey.
C: A what?
M: An ampersand.
C: What is a 'persand?
M: An ampersand is used in place of the word ... "and" ... in a sentence, when you, uh, don't want to write the word "and".
C: A persand is a place in a word?
M: Uh, no, it's a symbol used in place of a word. When you, um, learn to write sentences you will write the word "and" and sometimes, if you want, you can use ... an ... ampersand ...?
C: But does it have big muscles?
M: Yes. It has big muscles and it is very fast. It might even glow in the dark.
C: WOW! Persands are AWESOME!
Have a lovely day.
