You think this is a game Michelle? You were taught your positions for a reason. Whenever you are allowed to sit in a chair you sit up completely straight, and put your arms behind your back and stick your chest out by pushing your elbows together.
You’ve lost all privileges to sit in chairs until further notice. You’ll also be tied up like this in this chair for 24 hours to remind you that when you do not willingly get into your trained positions, you will be forced into them. Have a good night Michelle.
