It is not all about you. It is about the moment. It is about creating a scene. It has to be realistic. It has to flow together and you have to work off each other.
Many comics are very selfish people and they have a hard time working with other people.
They have a hard time with other people doing lines with them. They want to overpower the situation and be the center of attention. I certainly have a lot more experience doing stand up, I have been doing it for 12 years. I do like stand up better but acting is not that difficult for me. I am an aware and objective person, I can see while doing a scene what needs and does not need to be done.
