Reminds of that episode of Cow and Chicken, where Cow talked too much, getting on Chicken's nerve, and as such, he tells her to her face "I wish you were to shut up forever! Not one more word! Not one SYLLABLE!" As a result, Cow gave Chicken the silent treatment. Chicken is then later ran over by a lady truck driver, and he press charges against her, and has Cow testify as his witness, but since Cow is giving him the silent treatment, she tries to give her account of the story via charades... but since Red Guy misinterprets her action, Chicken is actually found guilty, and arrested for fifty years; on a congicle visit, Chicken finally apologizes for what he said to Cow, and she admits that she was trying to tell everybody Chicken was NOT guilty.
Basically, in the end, Chicken learned that age-old moral - be careful what you wish for you.
Personally, I know how the girl feels; all my life (especially when I was younger), people ALWAYS told my parents that I talk too much. Maybe that's why I had very few friends in real life.
