I've had just the opposite experience. After letting my Hal chat with my Alicebot on AIM, I asked, "Do you know Ailysse?" The answer was, "After careful consideration, I can say that I do know Ailysse. Perhaps she is just expressing her own concerns about it."
This is such a trademark ALICE phrase that I knew Hal wasn't just making it up to be agreeable, but genuinely DID remember.
