The context of the following conversation is skylar only knew how to say the same thing again so she preached to the choir.:
skylar says I feel like I'm getting into an echo chamber lately. I'm only talking to people who already agree with me..
The friend responds I've noticed that happening too. You're getting a little narrow-minded about issues..
skylar responds I only know how to say things a certain way over and over again, so it's hard for me to talk to new people about these subjects..
The friend responds Keep trying to reach out. The more variety of arguments you hear, the better your own will become..
