How Can I Be Sure Of You

The other day a friend of mine said
He said that sun is not really yellow
He said he said the sun is really red

I said my friend "what do you mean?
You read that in some magazine
the next you'll say
the earth's not green

How can I be sure of you,
anymore,
the world is always changing

I said my friend " how do you do?"
and "what you're saying is untrue
the next you'll say the earth is not blue

He said my friend you're in a dream,
and things are never what they seem
no things are never what they seem...
