Pocket-call protocol

You know those calls you get when someone sits on their phone or leans against their purse and accidentally dials your number? Some people call them pocket calls or butt dialing. I think I must get more of those than most people. With a name that begins with "Ba," my name must be near the top of the alphabetical list on most of my friends, family and acquaintances phone directory.

I don't mind getting random calls. In fact, when I get them as a phone message, I can't help but listen to most, if not all of the message. For some reason I think I might actually hear some juicy bit of information that wasn't meant for my ears. Like maybe the person calling will reveal how they really feel about me...or I'll hear some other sort of sordid detail that they want to keep hidden from the world. I'm like a rubbernecker passing a four-car pileup on the highway. I can't stop myself from listening to the whole muffled, jumbled and indiscernible message. Why can't I just hear the first few seconds and hit delete?

One day, my sister pocket dialed me about five times in a row. I stopped answering after the third one. What's the protocol here? Do I send her a text and tell her to lock her keypad? Do I call her back and leave a message that she needs to not lean on her phone so hard? Well...what do you do?
