How Can I Be Sure Lyrics

The other day a friend of mine said,
He said the sun's not really yellow,
He said the sun is really red

I said, my friend what do you mean,
You read that in some magazine,
Next thing you'll say the earth's not green

How can I be sure of you, anymore,
In a world that's always changing, rearranging,
Always changing, changing

I said my friend how do you do,
And what you're saying is not true,
The next thing you'll say the earth is blue

He said my friend you're in a dream,
And things are never what they seem,
No, things are never what they seem

How can I be sure anymore,
In a world that's always changing, rearranging,
Always changing, changing...
