Mom:

"I figured aliens would probably be number one.  There are enough things to be truly concerned about without some manufactured fear that aliens will attack the earth, and we'll have to somehow survive.  I believe your dad could survive by going from convenience store to convenience store, snacking on all the Twinkies. But seriously, there's more to life than just self-nourishment and survival.  Personally, I can't figure out why believing in aliens is so convenient, while so many important truths are often ignored, and seemingly so difficult to accept.  "
