You need to work harder on your deportment.
Have you noticed how some women eat in public? Adolescents and young women do it most and you are going to copy them. What am I talking about?

Covering your mouth while you eat. Use the back of your hand with your palm out and a limp wrist. Practise in front of a mirror.
Doesn’t it make you look sissyish, shy, girly? You will always eat like this, at home or in public, in company or alone.
