Things happen over time and people change but don't forget where you came from. No matter where you are now you were brought in the direction for a reason. There are people in your life that assisted you in your endeavors and don't forget them.
No matter what has happened in your family in the past that is all part of where we came from. Not all things are prim and proper but neither is life and we don't judge each other based on what our ancestors did. That is all part of who we are and looking back we can only act on the present.
