I am a sum of many you's. I am nothing on my own. I am a part of my home, my workplace, my family, the society I live in, the friends and relations that I have. All of them complete me. The person who thinks he is completely independent is unaware, or not ready to acknowledge the numerous linkages that he has within the universe. The same thought which makes me think that we are a small part of several other things...like people, articles, values, traditions etc. that means even when we are not there, we will continue to exist. So that means when someone else leaves forever, they manage to kill a part of us too - the part where we associated with them.
