Rough is one way to describe Alan.  He's also round and tends to be blue and red. Dave is a young person who often feels blue and cold. Eric has been blue because he's green with envy. If you come across a cold, red person with a round shape you'll find they are nice people. If you are green and also red, then you are young. I've noticed that big, blue people with rough skin are young. A rough person will also be a cold person. When you meet a person who is cold and nice, you can bet they'll be kind too. When I see a young child who plays rough on the playground with others and has cold hands, I know it means they are kind.
Alan is not rough.
