I’ve been asked so many times about certain things I do that I decided to explain.
- Extending and contracting your index finger while all others are contracted means yes.
- Extending your index finger and then moving it from side to side while all others are contracted means no.
- Extending all fingers, then taking the tips of them to your forehead with your palm facing you and doing a movement outward of about twenty centimetres means thank you.
