Your heart is full of sunshine,
It is where your smiles get theirs;
Your heart is brimming with love,
I love the way your heart cares.

My heart lights up like a star,
It's your love that makes it glow;
Your friendship lights up my heart,
Friend, I hope that this you know.

You don't light my heart with fire,
And you don't use batteries;
Lightning you never do use,
Nor other ways such as these.

You fill my heart with sunshine,
With your smiles' light that is fine.
