Have you ever wondered how some people are so spontaneous? They appear to be really quick on their feet and are ready to give an answer before you can wink an eye, or at the drop of a hat. They seem to know what to say just at the right time.
Spontaneity is another word for spontaneous, impromptu, someone who 'arises from a momentary impulse.' It is described mostly by doing something quickly without having a lot of thought behind it.
Some people may be spontaneous as it relates to going on a trip. They intend to stay for a few hours and then decide to stay longer or overnight. Some may decide to jump in the pool without being properly dressed in their bathing suit. Now that it truly spontaneous.
Some comedians are definitely spontaneous. They start telling jokes and it seems like they just get on a roll, telling one joke after another. They can stand on a stage and find an unsuspecting person in the audience and crack a joke that would cause the whole crowd to just bust out into laughter. They are so spontaneous that everyone sits in amazement and ask how did they come up with that joke so fast. They have such a uniqueness that not too many people have. They are just gifted and talented in the area of spontaneity.
Actors are spontaneous as well. They are given a script to learn their role and it comes so natural to them, it seems like it's in real life. They sometimes put their spin on the character and add impromptu words as if it's part of the script. That is really being a great actor when scenes are that was not in the original script. It somehow makes it feel so natural and not acting.
