you minus me

I tell you what I did, it's all trivial
I tell you what I thought, it's all bullspit
I tell you what I said, it's all in my head

I tell you what you did, thanx for your input
I tell you what you thought, you don't know jack
I tell you what you said, thanx for your input

You tell me what I did, you don't know why
You tell me what I thought, it's all bullspit
You tell me what I said, you don't remember

You tell me what you did, half the time
You tell me what you thought, you don't know how
You tell me what you said, I remember well
