Beware of the Dog p. 687

Yes, once i met someone, and she wasn't smiling at all and I thought she will be a mean and not nice girl. But it turns out that she is very nice, and we became friends. When people don't smile, they can be misled that they are not really that nice. Or on the other hand he or she can fake smile to let people think they are nice and it turns out they are mean. When you know this person more you will find out that he or she may not be the person you thought he or she was.
