When it comes to interpersonal communications, Cool Hand Luke said it best: "What we've got here is a failure to communicate." And that statement was never truer than it is for the two characters in Dear Son, Hey Ma. Even in the best of times, meaningful dialogue between a mother and son can be difficult or even nonexistent. But in the age of Facebook, Twitter and cell phone texting, personal communication doesn't stand a chance. Or does it? Dear Son, Hey Ma is a humorous, and sometimes poignant, attempt by a mother and son to communicate via emails.
