An unemotional person is someone who is not easily moved by emotions or feelings. This type of person can be described as an 'ICEBERG', meaning they are often seen as cold and unfeeling on the surface, but may have a lot of emotion underneath. They can also be likened to an 'icicle', which is cold and hard on the outside, but has a soft core. Finally, they can be compared to a 'STOIC', which is someone who is able to remain calm and composed in difficult situations.
