An archaeologist can tell a lot about a civilization from hundreds of years ago by digging up artifacts that were used by the people of that time period. Digging through layer after layer of earth to uncover pottery, jewelry, food and more. If you want to figure out why a certain person and or people are acting in an unpredictable or unsettling way,  you might have to work like an archaeologist to uncover the truth. It will take time and work but you can figure it out. It will be worth the betterment of that relationship... we all have a beginning to every problem, we all have those roots, they don't start from no where. Understanding ourselves, our friends and the people we love is key.
