I love: drawings and writings, from others and my own. Books, illustrated ones and not. Robots, metallic. Cats, better if they're ninjas or zombies. Stars and hearts (also in my skin). Colors, green is the best of them.
When someone is crying, of course, the noble thing to do is to comfort them. But if someone is trying to hide their tears, it may also be noble to pretend you do not notice them.
