Yes. This has two parts, the first part, always constant as you said, second part changing frequently as google search can show how vast is the variety (At times dangerously) but I guess the more accepted version is:
"Roses are Red
Violets are blue
Sugar is sweet and so are you".
But I went the version that says
"I am always happy; when I am with You".
So not expecting the second part of the "Say", Trena is officially the winner of this round.
Game is back to you.
