Proverbs and Sayings
Two wrongs don't make a right.
When someone has done something bad to you, trying to get revenge will only make things worse.
The pen is mightier than the sword.
Trying to convince people with ideas and words is more effective than trying to force people to do what you want.
The squeaky wheel gets the grease
You can get better service if you complain about something. If you wait patiently no one's going to help you.
