Who's heart does she get left with to mend?

Drop a hint or two,

here and there,

Just every now and then,

You shouldn't let it show to much though,

For then she would know,

Confuse her feeling's,

Play with her mind a little,

Tug on her heart some,

Show her all the things you never did before,

Just to get her to fall for you more,

Thats the way to do it,

As long as you keep your heart out of reach,

even if she's just your "Best Friend",

you seem as if that's ok,

But there's something you forgot to plan,

When she fall's for you,

Who's heart does she get left with to mend?
