Stephen King's It1990

Bill:
Audra, my brother who died...

Audra:
Yes, George?

Bill:
He didn't just die. He was m-murdered.

Audra:
Why didn't you ever...?

Bill:
Tell you? Because I forgot. Almost like it never happened. I know that this doesn't make any sense, but I have to go.

Audra:
But why?

Bill:
Because we made a pr-promise.

Audra:
Why are you stuttering like that?

Bill:
I don't know. I used to stutter all the time when I was a kid.
