3 words

There are only 3 words
i need to say
they don't hurt like a sword
and no their not gay

but they mean the world to me
and i want you to hear
and i want you to see
how much you mean to me dear

they start with a I
and end with a U
i know you have an eye
for these clues

their as easy as 1 2 3
and when i say them
they will make you free
and make yours eyes shine like a gem

i bet you can guess
what they are
it's not that big of a mess
and their not that hard

but when you figure out
what i have to say
those words i will shout
on that given day
