The police department posted the letter on Facebook, and it reads, in part, "Thank you for pulling my mom over because she deserved it. She took my phone away and I did not like it. She always brags about how good of a driver she is and it annoys me."
Eyewitness News isn't sure who the child is or how her mother responded, but we do know that the child attends Huggins Elementary School in Fulshear.
