May all your wish come true
have a tacit understanding; thoroughly understand each other, without having exchanged a word of explanation
First impressions are firmly entrenched.
He who strikes first gains the advantage.The best defense is offense.
ants on a hot pan
warn people by taking oneself as an example
pour oil on troubled waters; patch up a quarrel and reconcile the parties concerned
proceed in an orderly way and step by step; advance gradually in due order
be strict with oneself and lenient with others
Jack shall have Jill, all shall be well.
