I'm Not Sure Where to Put This So I'll Say It Here

You say yes, I say no,
You say stop and I say go.
You say goodbye and I say hello.

Hello 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.

I say yes but I can mean no,
I can stay until it's time to go.
