Safety Through Omission

Belle: Serial Killer is asking me to tell him what his best and worst qualities are.
Green Lantern: Uh oh.
Belle: Can I tell him I was afraid he'd chop me into bits if I let him know where I lived, but, other than that, he seemed like a perfectly nice guy?
Green Lantern: Don't agitate him!
Belle: hehe
...
Belle: Ugh. Now he told me mine...
Green Lantern: What? That you lied about having a boyfriend?
Belle: I did not lie!
Green Lantern: :-P
Belle: I was dating someone when I told him that... Just haven't bothered to update him...
Green Lantern: Fair enough.
Belle: Safety through omission.
Green Lantern: LOL
