No No

A name I used to call my cousin Noah, Noah, if you're reading this, I'm sorry, I was mean, I was selfish, I was inconsiderate! My tiny brain could not comprehend that you had feelings deep down in your soul, and that I had hurt them, damaged them, ruined them! This is an apology, to you, and any other people who are named Noah, and have a slightly younger cousin who calls them No No!

Hey No No, give me all your monopoly money or I shoot my nerf gun!
