Aside from the tongue, the heart is the most disobedient part of the human anatomy.

If I can teach this heart to stop
Loving you so much it hurts me,
Then maybe my brain that's on top
Won't ache from such frivolity.

Unruly emotions consume-
My heart beats a mind of its own,
Tell me when will my sleep resume?
This tired body wants rest alone.

Oh why can't the heart just obey?
In beating compliance submit
To wisdom my brain doth relay,
Not stressing it to the limit.

If I taught this foolish heart then
Not to see you and hear your voice,
You know I'll never love again,
A Stone Heart never had a choice.
