- Proxies add behavior (Aspected behavior added to the classes by the framework)

- in spring everything is proxied

- all classes in spring gets wrapped by at least one proxy

- proxies can only apply their behavior only when they are called by the proxy

- private methods dont get proxy behavior (since they are not exposed to the proxy)

- internal calls (reference method call on same class) dont get proxy behavior (since they are not exposed to the proxy)
