I Am An Island & She Is Only A Dolphin

She doesn't like to see a frown,
She only accepts a smile,
But I can't help it if I frown,
More than once in a while.

She doesn't like any bad words,
Not even ones like "crap",
But I can't help that we're not the same,
Maybe I should rap?

She doesn't understand me half the time,
She only knows herself,
But I can't help that I am different,
Because I am myself.
