The Muting

Had a 3rdLander being extra chatty the morning after the 3rd and last debate.  I talked to the 3rdLander a few times during the day. To no avail.  Finally I chided the child with a stern tone, "You said you were going to get this under control."  

The 3rdLander reached up with an imaginary key and locked up their mouth.  They said, "I'm muted.  Just like the president."
