The Butt Dial

Recently I have butt-dialed my friend MH a few times. What's the etiquette here? It's getting to the point where I feel I should remove her from my address book to spare her having to endure the inconvenience. Does anyone else's phone target one person? It must have something to do with her name or the number associated with her, because it happens all...the...time. Poor MH. Thoughts?
