There was a quiet moment.
"....that's it?"
"That's it."
Twilight nodded to herself. "Huh. Okay. Okay, sure, I'll... I'll try – "
"Also, could you pass the message on to the other loopers? It really is nothing personal, but when you can't tell if 'dear sweet YourOwnName' is an expression of affection it tends to get on your nerves after a while."

"No, it's fine. You didn't know."

"Swear by trees," Celestia suggested. "They're fairly reliable."
