It was once said that those of the Uchiha Clan do not feel emotions the same way others do. Seen as cold and hard, it is easy to mistake them for almost unemotional stones. However, much like the fire jutsu they are known for, their emotions burn hot. They feel everything so strongly that they have to put up stone walls around their exterior; simply to keep others from being burnt. Even their sharingan reflects this: being awakened from increased chakra flow (usually due to strong emotions). However, some Uchiha burn too brightly. This burning of emotions is exhausting. Constantly in love. Constantly in anger. These emotional flames are in no way a gift. They inspire hopelessness and misery. In the end, these flames will burn out; worn out by strain and stress.
