A person who has realised that their emotional reactions and opinions (and those of others) towards other people and events have little to no effect on the outcome of a situation. In short, they know that reacting emotionally to certain situations is totally futile . They have therefore made the obvious step of being unemotional about situations they have little control over, because it's a total waste of time . Girlfriend left you? Getting cut up about it isn't going to help. People making bitchy comments about you? Having a cry won't change anything. Being Stoic doesn't necessarily mean having no emotions at all, rather only reacting emotionally to things that truly matter and are of great importance to them. Stoics are often perceived as weird, cold and unemotional by others, especially during their teenager years, when most other adolescents have little control over their feelings. The Stoics of course know that others views on their Stoicism are irrelevant, because they will not change the fact that they are Stoic, nor will it help them understand it, so they don't really care. Some Stoics take satisfaction from the irrational, emotionally driven responses of their peers. Some women hate stoics, as they are very difficult to manipulate emotionally.
