My Little Pony: Friendship is Magic, Season 8

Mudbriar:
[to Unnamed Unicorn Mare #3] Goodbye.

Pinkie Pie:
 That's what you've been standing here all this time to say?

Mudbriar:
I was deciding between "goodbye" and "see you later".

Pinkie Pie:
Uh... but, they're the same thing.

Mudbriar:
Technically, they're very different. "See you later" implies an event in the near future wherein we see each other. "Goodbye" expresses good wishes where parting or at the end of a conversation.

Pinkie Pie:
Yyyyyeah, same thing.

Mudbriar:
I will not apologize for speaking with precision.
