Roses are red

Nowadays, roses
Can be pretty much any color
Thanks to genetic engineering.
I bet you  could even find ones that glow in the dark.

Violets are blue

But most people prefer violet violets.
So they tend to only come in violet.

Sugar is sweet

I don't really know what love is,
And my emotions are all shades of gray.
But I can't get your smile out of my mind.

And so are you

I bet you would never guess
How much I think about you
Because I am just part of the background.
I am a stranger to you.
