Life is negotiation & competiion

The only things you should do when your meets are not met is to increase the regret matrix for the other side. Let her/him to pay the higher price if she/he is gonna lose you. Respect the your opponent idea, but don't let her/him to believe just  hoping  the things stay the same , is gonna work. Don't leave anything fuzzy and remember things doesn't exist except in writing. Get somebody that has authority to negotiate.
