“It is unbelievable.”
“Unbelievable! You are unbelievable! First you ruin my life and then you blame it on my period!”
“If you know that I am an unbeliever, then you know me better than I do myself. I may be an unbeliever, but I am an unbeliever who has a nostalgia for a belief.”
“Local newspapers are directories of horror - unbelievably vile people doing unbelievably vile things to each other.”
“Be true, unbeliever.”
“You are unbelievably sexy.”
