Context: He agreed , but first wanted to dial into my computer , after which he giggled at my desktop background , which I happen to love : I , getting pissy , said " So now you know I ' m Catholic " which seemed a cue for him to launch into his own views . You 'll be glad to know that he believes in God , Jesus and the second coming . He seemed surprised that Arthur and one daughter are atheists and that I had n't made them Catholic .
