Can We Change

I have been spending the past eight months working on myself and making the necessary changes. It has been a very slow and difficult process but it is happening, or so I thought. Today I spent time with someone I wish would change but it didn't take long before I was treated the same way I was in the past and my first thought was "people never change." How can I feel that people never change while at the same time working to change myself?
