Many Americans find silence uncomfortable. They will talk continually to fill any pause in a conversation, even if it lasts only for a moment. If you are silent for long periods of time, Americans will do their best to include you in the conversation. They may ask you if you are feeling well or if there is anything they can do to help you.
