They told me I should leave you
I should walk away
And never look back--
You're no good for me,
I'll regret you someday...
But there's just so much about you
That makes me happy--
They just can't seem to see.
May be I'm in denial,
So for now, just let us be.

I actually wrote this poem about Pepsi, but it's quite applicable to many situations don't you think?
