text: If somoene is das you can see it nut you don't know how they feel inside. You can probobbly draw a picture of them or soemthing instead of using tecnology. Also any type of facial expression sould be valuable in the classroom. You can't really judge a book by it cover. So really there is no need of using tecnology to see somones looks or to make them that way. Everyone has differnt reactions to differnt things.
