your own neck: you are dependent on others
a thick neck: a lot of money
a thin neck: you deal with the wrong people
a slim neck: recognition and prestige
a fat neck: an intemperate life
have a bare neck: you will help the poor
have a hairy neck: happiness is just around the corner
have a stiff neck: open up to people, and what will be tomorrow, forget about what happened in the past
be hurt in the neck: the loss of dignity
