Hello; GOODBYE.

You say yes, I say no
You say stop and I say go
Oh, no
You say goodbye and I say hello
I don't know why you say goodbye
I say hello
I say high, you say low
You say why, and I say I don't know
Oh, no
You say goodbye and I say hello
I don't know why you say goodbye
I say hello
Why do you say goodbye?
Goodbye,
Oh, no
You say goodbye and I say hello
I don't know why you say goodbye
I say hello
