In every relationship there are similarities and differences between the two sides. Despite what may seem correct, when two people have too much in common it can be hard to get along. This is why the term "opposites attract" exists. Or the cheesy saying, "you complete me." One person is everything the other person is not, they fill in the missing pieces. 

The example I am portraying in my photo is the relationship between police officers and criminals. Police officers do not have a job without criminals breaking laws. Therefore police officers do not exist without their opposites. 

I showed this relationship by putting handcuffs on a police officer, this is ironic and shows that a police officer does not have a job without criminals to arrest.
