Arthur, Season 2 (1997-98)

Arthur:
I thought he was my best friend, but he wants to go.

Sue Ellen:
I bet he doesn't want to go.

Arthur:
He could have stayed and lived in a pit, but he said no. What does that tell you?

Sue Ellen:
Try thinking how Buster will feel. You're losing one friend, but everything else stays the same for you.

Arthur:
Yeah? So?

Sue Ellen:
Buster's losing all his friends and going to a place where everything is new. It can be scary. I know. We moved a lot because of my father's job. It's hard.

Arthur:
Buster probably needs a best friend now more than ever.
