When a person does something is for a reason

The roommate I had used to tell me about problems he kept having with people when he went out. I avoid people to avoid problems. I am not a child, I am an adult and I know what I'm doing. I worked with people for like ten years or more and I know that they are capable of causing harm. I also have had a lot of bad experiences with people including my family members and a lot of other Dominicans. People from other countries say that Americans are stupid and I've been seeing why for many years since I opened my eyes. They don't want to live clean and an NYCHA social worker told me to stop complaining because housing will never be clean, that's for you to see how stupid Americans are. Instead of looking for a way to make housing clean they ignore the problem.
