Some people are like that…
You have a concert to perform for kids. And parents are invited to stay. This is a talkative bunch. You get control and then you begin your story. Now the parents in the back believe that this is a concert only for children. So they continue to chat. Some people are like that.
At a pause between songs, the organizer of the event announces that the parents should keep an eye on their children and try to control them if they see them acting out or not paying attention. Some organizers are like that.
While you are performing, a parent comes up and stands right behind you. You do 
notice that there is a group of girls right in front of you chatting away, while you are singing. Your assumption is that the parent is trying to signal to her child to pay attention. Someone else in the crowd is taking pictures of you and after the event shares with you the picture of the parent that was behind you. The picture shows the parent with a camera in her hand trying to get the whole group of girls to look at her so she could take their picture… while you were performing. Some people are like that (luckily, not most people).
When you are invited to a class to tell stories. Some teachers decide that that is the time for them to catch up on all their paperwork and chat with colleagues that enter the room and assume that you are the disciplinarian for your performance. If you’re not modeling what you’re teaching, you’re teaching something else. Some teachers are like that.
Or when you’re playing music as students enter an assembly program to hopefully get the audience to come in quietly and listen, and the teachers and principals keep chatting and don’t think that musical interludes are part of the performance, so don’t control anyone. Some people are like that.
And finally some performers, choose to do what they are paid to do and perform for audiences no matter how attentive they are and perform for the people that came to listen and are listening, without letting the inconsiderate, disrespectful, people who have not been brought up learning how to be good and appreciative listener, affect what they are doing while they perform. I’m like that.
