Acting out script

To see if my script worked well and went fluently, I asked my 3 sisters and my cousins to read it in front of me. I wanted to ensure that it made sense and was a fluent storyline. After they read it to me, I felt as if it was a bit boring to listen to. It just sounded like conversations between 2 people. To improve, I wanted to include a few more people into the conversations to make it more interesting and have more going on, but I needed to make sure I didn't include too much to make it boring and feel like its dragging on. I decided to add another character to include in a couple of scenes with the parents, the new character is a younger sister of Jen's who annoys her and makes matters worse.
