Obeying Her Orders To The Letter
'SLAVE, TAKE OFF MY SHOES AND SNIFF MY SOCKS!'
A household footslave is only ever spoken to in harsh tones - shouted at; criticised; and given barked orders. And rightly so! Note too how the slave obeys his mistress's orders to the letter, leaving her dirty socks on her feet as he sniffs them, for he was not ordered to take off her socks.
