i can't guarantee it

my boss (aka pastor's wife - i need to think of a name for her, cuz it gets confusing) asked me on thursday that if i didn't like the job, to please tell her as soon as i can so she can replace me. on friday she told me that if i decide while i'm overseas that i don't want to come back to this job, she'd appreciate if i told her as soon as i decided. i don't know why she's worried, she has jasper's woo-woo brother there to tempt me if nothing else. i told her if i fall madly in love with a handsome stranger over there, i'll do my best to do it at the beginning of my trip so i can let her know sooner. but i did tell her i make no promises.
